What's Wrong?

what ever I try to do with Claude code on the desktop app it tells me this error:
Command failed: cygpath -u 'C:\Users\frezz\AppData\Local\Temp'

ALREADY TRIED:

• Checked wehre git is installed:

C:\Users\frezz>where git.exe
C:\Program Files\Git\cmd\git.exe
C:\Program Files\Git\bin\git.exe

• Reinstalled Git and Claude Desktop

What Should Happen?

It should do what the prompt says. for example read files, edit code.... basics
