It lasted about 30 seconds on the longest one, and, as the title says, the game immediately stopped working and closed. The error message was:
[File:C:\ci\buildAgent\work\uefork\Engine\Soure\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 176]
Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG')
I've tried to upload the minidump but only pictures are allowed?
