UE 4.24 and 4.25 constant RHI crashes... caused by tooltips and right click menu?

UE 4.23 seems very stable on my machine, but plagued by crashes on 4.24 and 4.25

Generally seems to happen when hovering over something in content browser (or BP editor) or right clicking on something in content browser.
I’ve had a google around, tried switching to nvidia studio drivers, making sure incredibuild is not installed - but I still seem to crash every few mins.

Screenshot showing black square where tooltip was showing up when dragging a folder: https://i.imgur.com/1YnGfKm.png

I may be speaking too soon - but this seems fixed for me.

Steps taken that seemed to make the difference

  1. download “Display driver uninstaller” Display Driver Uninstaller Download version 18.0.4.3
  2. reboot into safe mode
  3. run display driver uninstaller - fully remove nvidia display drivers
  4. reboot into regular mode (enjoying low res visuals on a 4k monitor)
  5. install geforce experience
  6. let it download the “game ready driver” - but don’t install it
  7. change to the “studio driver” - let it download then express install

Will post here again soon if the issue not fixed.

It helped me with just reinstall, my card doesn’t support studio driver. Thank you very much!
