Xcode keeps crashing whenever I try to run any .xcodeproj or .xcworkspace project.
Solutions I've tried are: reinstalling Xcode, deleting derived data, and deleting xcuserstate folder.
Xcode keeps failing with the below error:

Hints:
I have the same problem as you but on my side Xcode crashes only when I open a project directly from the fast project opening window (the one that opens when Xcode is launched) Try to open the project through the Finder or from the terminal directly with the command open /nameProject/xcWorkspace
I don't have any problems with this method.
