Hey! Just yesterday I was about to use my Wacom Intuos Pro to draw in Krita when the pressure sensitivity and the buttons on the stylus stopped working. When I looked into it, I figured out the Wacom driver (appeared to be) corrupted.
After reinstalling it, all the buttons and the pressure sensitivity worked fine when I tried in Photoshop, but the pressure sensitivity still doesn't work in Krita. I even tried a few different versions of Krita (I think I had 2.9 originally, then I tried the animation edition, not really sure about the version number, and then I tried 3.0.) Still nothing!
I'm at a complete loss and I'd appreciate any help!

If you tried both 3.0 and 2.9, then it's unlikely removing your krita config will help. (Some people report that that helped them out when a Windows update broke the wacom driver, though for the life of me I cannot imagine how that could have worked.)

If you install debugview and press ctrl-shift-t to start the tablet log, then create an image you can see whether Krita at least sees the tablet.

As for fixing the issue, I have no idea since I have never seen this issue on any of my Windows test systems
