Before codesigning, signing into my account worked normally, but after codesign it kept showing the "Couldn’t communicate with a helper application" error - I've tried restarting, delete Xcode and reinstall etc.

Posting here to try to confirm if others are experiencing the same problem on macOS Big Sur. If so, I guess there's no way to use XVim2 normally as it requires codesign? My thinking is keeping 2 copies of Xcode, one untouched to build to devices or upload to App Store, and another one codesigned to use XVim2.

Any ideas and suggestions appreciated!
