The crash occurs randomly during development and is reproducible across various projects.
Steps Taken to Resolve:
- Hardware Testing:
- Tested RAM with Memtest86 under heavy load. No errors found.
- Stressed GPU with multiple tools (e.g., OCCT) and confirmed stability.
- Verified CPU and cooling performance under load.
- Software and System:
- Reinstalled Unreal Engine and Epic Games Launcher.
- Performed a clean installation of Windows 10.
- Ensured the BIOS is up-to-date and reverted settings to default (XMP disabled).
- Project Settings:
- Attempted switching Project Settings → Default RHI from DirectX 12 to DirectX 11, based on community recommendations. However, the crash still occurs.
Despite all these steps, the issue persists. Unreal Engine crashes randomly with no clear triggers.
Request:
I would appreciate guidance on:
- Whether this is a known issue with Unreal Engine on similar configurations.
- Potential debugging methods or logs I can provide for further investigation.
- Any settings or configurations that might help resolve this issue.
Thank you for your support.
