Immediate hard crash on launch after connecting inconsistent wiimote, unable to reset

[shuttah627]

Hi! I'm experiencing a new hard crash on startup where the window shows up white for about 3 seconds and then everything closes.

The last thing I did with WiitarThing was connect a wiimote that was having a hard time recognizing a connected guitar. It was flashing between the wiimote icon and the guitar icon in the connected devices menu.

I was able to get an error log from the app, It reads as follows;

Has anyone else experienced this error? If so, how did you pass it? I'm straight up locked out of WiitarThing until I find a way to completely wipe the program from my computer (replacing the files with a fresh download of 2.7 did not clear the error) :(
