Steps to reproduce

Create a helloworld.ps1 file:

Expected behavior

Start Windows Terminal correctly.

Actual behavior

Looking at the use of Windows Terminal, I speculate that this problem is caused by an error in parsing the command line.

If you start wt as follows, you can run it correctly:

wt -- pwsh  -NoExit -File %CD%/helloworld.ps1
