Sample command line:

sudo codesign --force --deep --sign - /Applications/*.app

If you could replace the signature with terminal and app still crashed, just remove app with appcleaner (it is free to download), then, re install that app from app store

If you could not replace app signature, you have an invalid command line. Lookup for right command line for app specifically.

(Optional: look up more information about crash report and search for solution for listed issues)

In my case, every app works fine before I re-install MacOS (as I change new hard drive), but after reinstalling, every app from app store crashed (Garage Band, iMovie, VLC...)

I use meth
