I had an issue like this, may or may not help you
(File → Studio Settings) or (just press ALT+S) → Graphics Mode → Automatic
Can also adjust the Editor Quality above. [if your PC is good, this shouldn’t matter]
My issue was my graphics were on Vulkan from my old PC, and when I got my new one I had to change to automatic in order for studio to be useable
Refer to this if you still have issues
