Debugging script with breakpoint fails if PS profile sets ErroractionPreference to Stop

[theGeorgew]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

Set the profile's EAP to stop
Set-content -path $pshome/profile.ps1 -value '$ErrorActionPreference = "stop"'
Debug a Powershell script that has a breakpoint set
Observe the Powershell terminal prints an error importing the DSC module.
The script will also not stop at the breakpoint.

if you rollback the version of the Powershell Extension to the previous release the error does not occur
code --install-extension powershell-2023.5.0.vsix --force
I saw that this issue was merged for the release that is causing the bug: #2020
I see there were changes made to the loading of the DSC module that is failing to be loaded in the error
https://github.com/PowerShell/PowerShellEditorServices/pull/2020/files#diff-df2c1977dd89746b4b394dc2e26725467d330545813bf2bbc3383476693de476R94-R97

Expected behavior

I can debug scripts with breakpoints and it stops at the breakpoints without throwing errors in the terminal

Actual behavior

When debugging scripts with breakpoints it does not stop at the breakpoints and throws errors in the terminal

We'll just have to override $ErrorActionPreference during this code path.

[andyleejordan]

Ok so this is the code we're using to import that module:

                PSCommand psCommand = new PSCommand()
                    .AddCommand("Import-Module")
                    .AddArgument(@"C:\Program Files\DesiredStateConfiguration\1.0.0.0\Modules\PSDesiredStateConfiguration\PSDesiredStateConfiguration.psd1")
                    .AddParameter("PassThru");

                IReadOnlyList<PSModuleInfo> dscModule =
                    await psesHost.ExecutePSCommandAsync<PSModuleInfo>(
                        psCommand,
                        CancellationToken.None,
                        new PowerShellExecutionOptions { ThrowOnError = false }).ConfigureAwait(false);

                isDscInstalled = dscModule.Count > 0;
                logger.LogDebug("Side-by-side DSC module found: " + isDscInstalled.Value);

I'm testing some stuff...strangely I can get the error to show up, but I can't repro where it causes things to crash, even with '$ErrorActionPreference = "stop".
