What should I do? Buttons are invisible but still clickable (opens in new tab)

I'm experiencing severe UI visual corruption on Windows 11 with versions 5.x and 6.x, where buttons are completely invisible but still clickable, which makes it difficult to navigate or use the software properly. The buttons appear to have lost their visual styling, rendering them invisible on the screen, yet they remain functional when clicked, causing confusion and frustration when trying to perform tasks.
