See my answer below for the fix

I have exacly the same problem on my laptop with windows 7 installed.
On my main PC with windows 10, crash doesn’t occure.

Any solution?

i’ve got windows 10 and that’s where the crash is happening. I’ve searched for updates for graphics and windows but says my pc is up to date. and in the log file it has the error ‘DXGI_ERROR_DEVICE_REMOVED’ which i think is something to do with direct x? haven’t found a fix sadly.

same problem here any one found a fix yet

ok, ive reinstalled windows currently reinstalling unreal. i’ll let you know if it works

i’ll let you know in an hour or two when everything is finished :slight_smile:
