Hello @GrizzlyGabriel and welcome to the forum!
Usually this happens after Windows updates, whether it is an update for which you have to restart the PC or one of the updates that are installed without restarting and unnoticed, âbehind your backâ, is irrelevant here.
Uninstalling and reinstalling Krita is the biggest waste of time in the world, Kritaâs settings files and resources are separate from the installation, and that is for a very good reason.
Kritaâs program files can only really be damaged by malware infections or a very extreme system crash, so in the years Iâve been supporting users with Krita, reinstalling Krita has only been helpful 4 times (and usersâ PCs had other, bigger problems), thatâs round about 0.0001% of all cases where it helped.
Regarding reinstalling graphics tablet drivers. Experience has shown us that after uninstalling, according to the manufacturerâs instructions, a PC must be completely shut down, i.e. the power must first be switched on again to restart! Hibernation should be bypassed if possible or switched off so that the PC does not restart with the same memory state that it had when it was shut down (this is where the âblessingsâ of modernity bite each other in the backside (Hibernation should also be switched off anyway if you use SSDs (and love your SSDs) in order to significantly extend the service life of the SSDs!))
The same applies after reinstalling the driver, the PC must also be restarted using the power switch after it has been shut down to switch it off.
Please be sure to observe the manufacturerâs instructions in the manual whether the graphics tablet may be connected to the PC during installation, must be connected, or should never be connected!
This may sound like computer voodoo, but strangely enough it has often helped to reinstall the drivers that have just been installed without this power-off restart procedure in this way, but probably only Microsoft knows why this is so, but they probably donât know either.
If you want to reset Kritas settings, you will find the file kritarc in the folder %LOCALAPPDATA% on your PC. To do this, close Krita, then enter %LOCALAPPDATA% in the address bar of your Explorer and confirm your entry by pressing the Enter-Key.
You will then find the file kritarc, with a few other files that have krita in their name, at the end of this folder, but not in one of its subfolders! It is best to move all files with krita in their name to another directory, then Krita will recreate all files the next time it is started, but at least the file kritarc must either be renamed or moved from there, that is the file where Kritaâs settings are stored in, and it is good to have a backup of that kritarc in case it gets corrupted and needs to be renewed, this spares you the time to recreate Kritaâs UI to your liking.
If you have not yet activated the display of file name extensions in your Explorer, you MUST do so under Windows 11, as Microsoft has cut further capabilities from its crippled OS. You can activate the view of the extensions in the âViewâ menu of the Explorer, there is a checkbox on the far right of the menu bar, you may also want to activate (at least temporarily) the display of hidden files and directories.
Uninstalling resources should not be needed usually (it is nearly as seldom as the need to re-install Krita, maybe you need to add an extra zero 
). But rebuilding Kritaâs resource cache is a thing that could be of help more often (and it is not so tedious).
You can find Kritaâs resource folder by entering %APPDATA%\krita\ in the address bar of the Explorer and confirming this entry with the Enter key, this command will take you directly to Kritaâs resource folder. The ââresourcecache.sqliteââ can be found at the very end of that folder, there you can rename the file ââresourcecache.sqliteââ to ââresourcecache.sqlite.oldââ to let Krita rebuild its resourcecache (this only works if Krita is not active).
So, and now I have to retire for a while.
