UE 4.21.2 UI and details appears blank or do not show

My editor seems glitched out, the tabs at the top some are hidden and details of props are all blank. as I click they appear and disappear after a second, any idea?

I had this issue too and discovered it was caused by a recently enabled plugin, which was created for some new hardware. I no longer need the plugin so I was able to disable it and remove it from the project to fix this issue.
