Have you try'd to delete the built-in folder ??
Normally placed at
TC should be shut of when doing so, it will delete your personal settings, so you will need to set up cfg(UI) and Template etc again when you start up TC again, the Built.in folder will rebuilt itself.
If that not help i would do it again, but this time close your pc, wait 10-15 sec and restart pc, then run a repair of TC in windows apps and features and finally start TC again after that.
If you use the Sun in Geo Location, uncheck it, as there was some issues about that in an earlier version and i believe it was in v 21.
