Your display seems to be pretty small, why is that? Is your Krita really big on screen? Have you tried: Configure Krita -> General -> Window -> uncheck Enable HiDPI, restart Krita and see if you can use it that way?

Well I have it checked but I can't uncheck it, as the button to apply the settings isn't on my screen and to get it on the screen I would have to change the vertical size of the window but then the bug I mentioned occurs. Should I reinstall krita?

Sorry, but displays smaller than 1366 × 768 are not supported and will not be supported.

Go to your Windows settings and change the UI scaling to something smaller, because I doubt your screen is actually that small, I think it's Windows making everything bigger. Then you can uncheck the setting in Krita and restore the Windows settings, or just leave it as it is. Although if you really need such big scaling and otherwise you don't see buttons or can't read what's going on on your screen (because of weak sight etc.), it might be that Krita is not a good app for you at the moment :(
