Startup Slooow at Global Settings

Suddenly Nuendo startup hangs for a couple minutes at the point of loading Global Settings. Even longer delay within Preferences when accessing the Presets button.

Removing/renaming the User Settings folder solves it but then there’s the huge hassle of replacing all the customized settings, key commands, etc.

Not for the first time. I’ve yet to figure out what triggers the problem (“I didn’t touch anything!”)

Instead of trashing the whole User Settings folder is there a particular file/s to remove or some other way to streamline this process.?

Thx
