Unreal Engine 5.3.2 Launch Bug - Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000001440

Question

UPDATE: I think the root of the problem is here: It can`t see my NVIDIA GeForce GTX 1050, or it is broken, so that is probably the reason.

After launching Unreal Engine 5.3.2 this is what I get:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000001440

UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_D3D12RHI UnrealEditor_RHI UnrealEditor UnrealEditor UnrealEditor UnrealEditor UnrealEditor UnrealEditor kernel32 ntdll

Interestingly enough, I am able to launch my projects through Epic Games or from the project folder directly => the project is launched successfully in UE5 and I can proceed working there. However if I launch the app itself, Unreal Engine launcher, the above mentioned error occurs.

I am also getting this notification in the project: Missing support for advanced rendering features

Moreover, somehow lots of games, Unreal Engine based, started having lags. Dead by Daylight for example has recently moved to Unreal Engine and I can`t play it without lags with lowest settings possible. Mordhau had always been fine, but yesterday I checked it and attack animations were broken. Unreal Engine app itself has become much more laggy as well.

I tried various methods, reinstalled UE5, tried some shamanism with Config .ini files, etc. Nothing has helped so far.

I can assume smth is wrong with my gpu. I am not a Computer Science professional, neither am I an experienced game dev, I have only recently started diving into this, so please don`t judge too harshly.

Thanks in advance.

This is related to your DirectX. You must check your graphics is at least in minimum requirement category and if so update your drivers.
