I have these errors from files that I have not made any changed to.
I have tried regenerating Visual Studio files.
I also uninstalled/reinstalled Unreal engine and Visual Studio.
I originally started with Visual Studio 2019 but when I started getting these issues, I did update to Visual Studio 2022.
One post I found said the issue was resolved by going to the Visual Studio Installer → Visual Study Community 2022 → Modify - Individual Components → uncheck IDE Support for Unreal Engine. but this did not resolve it for me
Another post suggested Click Edit → Editor Preferences → Source Code
Change Source Code Editor to “Visual Studio 2022”
Click Tools → Refresh Visual Studio 2022 Project
Click Tools → Open Visual Studio 2022 to open the project in Visual Studio
I have tried opening various UE5 projects but the errors persist even when no code/classes have been added.
I'm lost in this dark world any help is appreciated!

Coming from a comment I gave to the original question:
The "Error List" window in Visual Studio does not work well with Unreal, due to parsing issues of IntelliSense. The best way to see if an Unreal project builds seems to be to just build it and ignore IntelliSense alltogether. In this case, it is best to set the dropdown in the "Error List" window to "Build" instead of "Build + IntelliSense", to filter out any errors that just come from IntelliSense.
I found to just ignore the "Error List" and just work with the "Output" window to be a good solution as well, but that's just preference.
when i try to rebuild the sample or the plugin, i have some errors in the visual studio console

those the three errors i got when i try to build in visual studio
in context to building the project, which of these build descriptions fit your situation?
Is this during:
the initial project opening ie: "build agora modules?"
packaging/building the project to test a standalone build.
Thanks!
Using Visual Studio 2017 RC, I get this compile error:
LINK : fatal error LNK1181: cannot open input file 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.10.24728\lib\x86.obj'
x86.obj does not exist on my system. Yet, the compiler wants to link to it, although I have not instructed so in the project properties. Does it misinterpret a folder name ($(VC_LibraryPath_x86)) as an object to which it has to link? Could it be a bug?
On the other hand, I found out that a similar problem also occurs in Visual Studio 2015, there is even an (unanswered) question on it: LNK1104 cannot open file '...lib.obj'
Does anyone have an idea what is going wrong here? Thanks.

I no longer can compile any c++ project. When i try to compile anything i get following errors:
Error 101 error MSB4018: The "CL" task failed unexpectedly.

Projects in other languages i.e C# are working fine.
Does anyone had similar problem to mine? What is the solution? I tried reinstall .Net framework and Visual Studio itself.
Try to enable browse information generation by adding flag /FR or /Fr. it might work for you.
To enable it you can follow below link:

I have a very simple C++ application.
#include <stdio.h>
#include <iostream>
int main(int argc, char argv[]) {
cout << "hi" << endl;
}
When I compile for the first time in debug mode, Visual Studio complains "Unable to start program ..\Debug\myprogram.exe. The system cannot find the file specified."
However, I think that this is obvious because I am compiling for the first time, right? This executable should not exist yet, so why is Visual Studio balking at compiling?
Thanks for your help.
Also, when I build, the following log appears:
When I build (Build->Build solution.), this log appears:
1>------ Build started: Project: print_digits, Configuration: Debug Win32 ------
1>Build started 12/23/2011 4:32:17 PM.
1>InitializeBuildStatus:
1> Creating "Debug\print_digits.unsuccessfulbuild" because "AlwaysCreate" was specified.
1>FinalizeBuildStatus:
1> Deleting file "Debug\print_digits.unsuccessfulbuild".
1> Touching "Debug\print_digits.lastbuildstate".
1>
1>Build succeeded.
1>
1>Time Elapsed 00:00:00.08
It says build succeeded, but no executable is being built for some reason.
A couple of problems here:
1) This error is about trying to RUN the program, not compile it:
"Unable to start program ..\Debug\myprogram.exe. The system cannot
find the file specified."
2) Probably the reason it can't find the program is because it FAILED to COMPILE.
Here are the errors I got from your source:
tmp.cpp(5) : error C2065: 'cout' : undeclared identifier
tmp.cpp(5) : error C2297: '<<' : illegal, right operand has type 'char [3]'
tmp.cpp(5) : error C2065: 'endl' : undeclared identifier
tmp.cpp(6) : warning C4508: 'main' : function should return a value; 'void' return type assumed
You should be able to fix these particular errors if you add "using namespace std;"
Get a clean compile, and you should be able to run the debugger :)
I had the same Issue. The problem was that my antivirus (in my case Avast) was automatically deleting the file on creation. And because I had Avast on silent mode it did not notice me about the deletion. So disabling the antivirus or setting up a exclusion rule helped in my case.
Need to write after the includes
using namespace std;
I have the same problem with Visual Studio 2015.
If I have a solution with 2 projects and set the Output File in Linker->General to $(IntDir)$(TargetName)$(TargetExt) then it builds an .exe file (I have verified it exists), bit I cannot run it via Visual Studio.
I currently don't have a solution to this problem, other than reverting back to $(OutDir).
The current problem is that both projects produce the object files in $(IntDir) but I get two different .exe files in the same folder.
Once I've tried to change the output location, I've been unable to get the debugger to execute the .exe file through Visual Studio, so I suspect I will need to edit the .sln or .vcxproj files to fix the problem.
Unfortunately Visual Studio is buggy and might require editing the xml files directly in these situations, if these are the problems you are experiencing.
I got a similar error when I didn't declare the libraries I was using correctly in "properties".
I think what I had to do was write the names of the .lib files in Properties/Linker/Input/Additional Dependencies and set the paths in "VC++ Directories". But you shouldn't get that problem with just stdio and iostream.
Same problem had faced, after some RND finally i found the solution.
Solution-Go to project properties->Security Tab->Uncheck "Enable ClickOnce Security settings".
