RX 7900 XT Unreal Engine 5.1 Path Tracer crashes

Hello! I have resently purchased my new AMD card to use it for visualizations in Unreal Engine (specifically with Path Tracer).

Unfortunately, both in viewport mode and with Movie Render Queue I'm constantly getting GPU Driver Crash. None of the solutions from UE Documentation (https://docs.unrealengine.com/5.1/en-US/how-to-fix-a-gpu-driver-crash-when-using-unreal-engine/) helped. The issue is related to Dx12.

At the same time, Lumen environment and reflections system works well both in Viewport and MRQ, as well as Path Tracer in Twinmotion.

Driver version 23.1.1

Really wish someone from AMD would respond, its been the same thing with Unreal 5.2 and 5.3. The issue is only specific to Radeon because after further investigation into the problem, people with other GPUs brands claim they aren't having any issues.

Same issue here with Twinmotion and the RX6800XT. Tried everything and contacted Epic Games. According to them the issue is specific to AMD, and they made aware AMD of that. I wish too AMD would finally fix this issue.
