I have something similar, still not solved.
Look at the Event Viewer->Windows Logs->Application.
Mine shows this:

(if yours is a different problem, let me know and I'll open a new issue to avoid hijacking this one)

I was having a similar issue with UXTU immediately crashing after startup and found my solution on Discord:

"Delete the AATUV3 folder found in either AppData/Local or AppData/LocalLow" -JamesCJ

It seems to reset your settings though, so make sure you backup your settings before deleting the folder.

I’m currently clearing all UXTU V1.0.0 issues now that UXTU V2.0.0 is in beta testing. If the issue still persists in UXTU V2.0.0 feel free to reopen the issue.
