Steps to reproduce

Opening this on behalf of a customer.

1. Create a simple dummy PowerShell module (e.g: error-test.psm1), containing this:

Function Test-Error {
    $errorMessage = "Line1`r`nLine2`r`n"
    Write-Error -Message "`r`n$errorMessage"
}
    
Function Test-ErrorWrapper {
    Test-Error 
}

2. Import the module in your current PowerShell session:
   Import-Module <path to>\error-test.psm1
3. Run the Test-Error function, everything works as expected.
4. Run the Test-ErrorWrapper (just calling the other function) & the error message is displayed without any line breaks.

Note: if you change $ErrorView to NormalView then the line breaks are displayed as expected, along with the "full error details".

Expected behavior

Test-Error displays the message as intended.

PS C:\> Test-Error
Test-Error:
Line1
Line2

Actual behavior

Test-ErrorWrapper displays the message without the line breaks, everything on a single line.

PS C:\> Test-ErrorWrapper
Test-Error:  Line1 Line2

Error details

No response

Visuals

When $ErrorView is ConciseView (by default in PowerShell 7+), line breaks are missing/removed:

When $ErrorView is set to NormalView, the line breaks are there & the message is displayed as intended, along with the "full error details".
