Truffle installed but not working properly

I'm using node version 12.20.2 and npm version 6.14.11 and installed truffle with cmd as administrator, the truffle framework version 5.5.12 has been installed but when I run any command in the vs code, it pops up with an error

I don't know what to do with this

On the truffle quickstart, it states to use nvm, as permission errors like this will occur. However, to solve this error, you can also use this powershell command Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Hi My problem is with the terminal VS app

PS E:\learning\project\django\env\scripts> activate

Navigate to Venv environment and run:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUse
then run:
.\\Scripts\Activate.ps1
this should activate your venv environment
to deactivate:
deactivate

Errors using AWSPowerShell in PowerShell

I am trying to work through the instructions on getting started with AWS IOT here. I have installed the prerequisites:
Windows 10
Visual Studio 2017 with latest updates
Windows Subsystem for Linux
But I think the page leaves some important things out. To use PowerShell I have to have some kind of AWSPowerShell or AWS Tools installed. When I run '.\provision_thing.ps1' it does some of the things but fails at Register-IOTThing and Get-IOTEndpoint. The errors I get are:
Register-IOTThing : The 'Register-IOTThing' command was found in the
module 'AWS.Tools.IoT', but the module could not be loaded. For more
information, run 'Import-Module AWS.Tools.IoT'. At

Get-IOTEndpoint : The 'Get-IOTEndpoint' command was found in the

information, run 'Import-Module AWS.Tools.IoT'. At

char:17
$EndpointName = Get-IOTEndpoint
CategoryInfo : ObjectNotFound: (Get-IOTEndpoint:String) [], CommandNotFoundException
FullyQualifiedErrorId : CouldNotAutoloadMatchingModule
When I try to run 'Import-Module AWS.Tools.IoT' as the error suggests I get:
Import-Module : The specified module 'AWSPowerShell' was not loaded
because no valid module file was found in any module directory. At
C:\Users\erics\source\repos\iot-dotnet-publisher-consumer\Dotnetsamples\provision_thing.ps1:1

If I attempt to install AWSPowerShell using Install-Module -Name AWSPowerShell I get a quite impressive and long error truncated here:
PS

How can I clean this up and get access to AWSPowerShell in PowerShell?

Attempting to install AWS Elastic Beanstalk getting: ObjectNotFound: (C:\Users\Ameer:String) [], CommandNotFoundException

I'm following the instructions on the ELB github
I first run the following command :
git clone https://github.com/aws/aws-elastic-beanstalk-cli-setup.git
but I'm encountering the following error when I run the second command
.\aws-elastic-beanstalk-cli-setup\scripts\bundled_installer
I'm using windows 10 and running the commands through cmd, however powershell gives me the same issue.
The error:
