hi @lucoiso
The problems is probably due to the DX12 drivers that driver your graphics card the shaders probably cannot build and suspend
In 5.3 the default is DX12/ SM6.
You could try delete the shaders built onfirst startup
C:\Program Files
Epic Games\UE_5.3\Engine\DerivedDataCache\Compressed.ddp
I would follow the post which was earlier
#UE5 CRASH #UE5 Unreal Engine 5 Crash
You could try updating your Nvidia drivers need version 537.* is latest from GeForce Experience and would explain why Fornite has a problem
