#help krita

first off, WHOOPS spoiler for a big piece I'm working on!

Secondly, I'm having an issue with krita and it makes it impossible for me to work, would you guys be able to tell me if it's a setting I accidently triggered, or if it's a legit bug?

I've tried closing (with Task Manager) and opening, restarting my computer, seeing if it's the same with other works, and nothing seems to work. I haven't tried uninstalling and reinstalling Krita, because I'd first like to know if there's a simpler solution

I really need this fixed, cause it makes it impossible for me to work properly

thank you guys in advance!
