Mojave: apps crash on launch and when searching menu items

Currently I have the situation that a few apps crash on launch (amongst others Things, Google Drive File Stream) and every app crashes when you search the app's menu items through the help menu item. I looked into the console and almost all of them have a variation of these error messages:

The issue has something to do with my user account, as on a newly created user account the problem doesn't appear to happen. I already tried reinstalling the computer but that also didn't solve the problem.
