That crash is fixed with https://github.com/EpicGames/UnrealEngine/commit/1b37202f41a9064659d7a26f1c13a491489c5ed5
This didn’t work for me. I’m using DX11 currrently
I just resolved my error by removing blueprint code I had written to start the game in fullscreen.

I’m getting a similar error, DX11
Can confirm, also getting this crash in 4.23.1,
dx11,
while full screen try alt tab, it will crash the engine…
For anyone running into this, the fix posted above made it into 4.25
