Windows Terminal version

1.25.260109001-llm

Windows build number

10.0.26100.0

Other Software

PowerShell 7.5.4

Steps to reproduce

Run the PowerShell script from the Windows shell like this:

d:\windows_terminal\version\wt.exe --window last new-tab --inheritEnvironment --profile 'PowerShell' d:\powershell\version\pwsh.exe -NoExit -NoLogo -ExecutionPolicy Bypass -File d:\get_version.ps1

Expected Behavior

The PowerShell script is executed in new tab, and then the work continues in the same tab of the Windows Terminal console (for example, typing and executing other commands).

Actual Behavior

The PowerShell script executes successfully, but after clicking on the current tab window of the Windows Terminal console, this happens: Windows Terminal Host is not responding.
