ShowUI not working

[ChuckM2]

First, I want to thank you. Your script was the only thing I could get to work without crashing for Windows 11 ISO files.

When I tried the -ShowUI setting, it did not work and these are the errors that I saw. (Command line without -ShowUI did eventually work.) I was able to browse to the ISO, pick the "edition" of windows from the drop down" and hit the create VHD button before the last messages. No VHD was produced.
