Hello everyone, I have a problem.
When I try to launch my game in fullscreen (The Cycle on Epic Games) what's made on Unreal Engine 4 — always crashed.
This is how it looks: View: https://imgur.com/a/qzjx3rG


This is text what's in Crash Reporter:
EpicAccountId:SHN3RT

As the RHI appears to be failing with DX11, it may be worth a try to force DX12 via the command line in the shortcut used to start the game.

This will probably crash the 1st time run as shaders will have to be rebuilt.
It doesn't work but I found a solution for this problem.
If I want to turn a game I have to set a window mode in shortcut of game.
It's stupid solution, but works!
Then, I can launch a game and in game set to fullscreen windowed to have game like you play in fullscreen mode.

Thank you, I appreciate your help. Thanks!

Just a point of clarification, this is from your AppData\Local\EpicGamesLauncher\Saved\Logs directory?
No, this is copied text from Crash Reporter. But if I click click here to view directory the file log is in AppData\Local\Prospect\Saved\Crashes\UE4CC-Windows-6B0622F642E8A49EC7F947AC8F7A3733_0000

If you need I can send files The Cycle.log and EpicGamesLauncher.log later.
