ToonBoom Extremely Slow startup

I recently upgraded to the latest version of TB Premium(22), from 17. Since doing that, it now takes about 3-5 minutes for the program to open. Even if it's just the program itself and not an actual file, so it isn't an issue with the file being heavy with rigs and what not. No other program opens this slow on my computer, so I am not quite sure what the issue is.

I've tried uninstalling and reinstalling. Tried reinstalling on a different drive to see if that helped... but nopes. :(

I'm running the latest version of TB on Windows 10 desktop. I have 2 SSD cards with more than 500 gigs of free space on both. 32gb of RAM on 11th gen intel core i7 at 3.6ghz

If anyone has had this issue and figured out how to solve it, advice would be greatly appreciated!
