Why blueprint window editor just dissappear?

Looks very much like the Nvidia driver bug:

Right-Click Menu / Tool Bar Menu Disappearing?

Could you maybe write out what this fix was? The link you posted no longer works, and I’m having this same issue! From context clues it seemed to be about the nvidia colour settings, but I change from ‘default’ to nvidia and it didn’t seem to fix the issue? Do I need to do something else?
