Visual Studio Code C++ debug break on exception

I am running visual studio code with the C++ v1.7.1 extension installed
The launch.json file specifies cppdbg

I want to break when and where an exception occurs. However, I cannot find where to enable this. There are no exception checkboxes in the breakpoint panel.
Running on windows 10 using mingw g++ v11.2
How do I enable break on exception?

It was GDB.exe here earlier, But it said it couldn't find it , Even I couldn't find it..
So I put gdb32.exe as i was able to find that out , But it still didn't debug anything
i am fed up of this problem now...
Code Blocks says Please specify executable path,It can't be found
Please help, Thanks
Code::Blocks can be installed without MinGW, which is okay as MinGW-w64 is much better maintained. But MinGW-w64 needs to be installed separately.
You can download a standalone MinGW-w64 from https://winlibs.com/ and the site also explains on how to add this compiler and debugger to the settings.

VSCode not compiling c++

Im running Ubuntu MATE and i program in C++. I wanted to transfer to vscode so i installed it. But overall i cant really compile or debug anything. This works in terminal to run a code.
g++ HelloWorld.cpp -o HelloWorld.o
./HelloWorld.o
But if i want to go through button to compile this thing happens. What should i do? Im adding launch.json down below.

If anybody in the future wonder what was the solution, compile c++ under linux with g++ and then press ctrl+f5. That one solved my problem, couldnt figure it out for 2 days.

dbg not working on VScode with WSL2 - Unable to resolve non-existing file 'vscode-remote://wsl+ubuntu-20.04..'

I've installed WSL2 and build tool and everything is working well on linux console (including a test c++ program I was able to debug with dbg).
I'm now trying to have a working development environment on my windows10 machine, by installing VSCode and a couple of extensions (c/c++ and Remote WSL).
Build works just fine, but when I try to debug, after executing (F10) a couple of lines I get the error:
Unable to open 'libc-start.c': Unable to read file 'vscode-remote://wsl+ubuntu-20.04/build/glibc-YYA7BZ/glibc-2.31/csu/libc-start.c' (Error: Unable to resolve non-existing file 'vscode-remote://wsl+ubuntu-20.04/build/glibc-YYA7BZ/glibc-2.31/csu/libc-start.c').
From that point on debugger basically doesn't work anymore, every time I press F10 (or F11) I get a new popup with the same error
screenshot of error and dev environment
Pressing the "Create File" button results in an "Unable to write file 'vscode-remote://wsl+ubuntu-20.04...." (same file as above).
here following my launch.json file

I've searched quite a bit before posting. Other have had similar problems in older posts but most of them claimed that being an old bug and they say the problem was solved with the upgrade. I'm running latest version of everything I'm using (including VSCode and the plugins).
thank you in advance to anyone helping out.
Adding
"sourceFileMap": { "//wsl$/Ubuntu-20.04" : "/" }
to the launch.json resolved the problem for me.

Proble in debuging c++ code with visual studio code, with lunch.json file

I have Problem in debugging c++ programs in Visual studio code. Although, debugging was working before. I had not change any configuration or setting. When i opened visual studio code today then i saw that error.

I have not changed anything in system/vc code/ configuration etc.
Then, why debugging stops working.
The program setting specifies the program you want to debug. Here it is set to the active file folder ${fileDirname} and active filename with the .exe extension ${fileBasenameNoExtension}.exe, which if helloworld.cpp is the active file will be helloworld.exe.
The main problem is vccode is not able to find the current file for debugging.
These are some links that might work for you.
