Hello all,

I’ve been trying to troubleshoot an issue I’ve run into and am running out of things to try. Whenever I try to play any level I see the same crash every time, without fail:
Fatal error!

Here’s what I’ve tried to troubleshoot:

Created a new project, did not make a single change and just tried to play it (FPS) and it crashes.
Tried creating a 3rd person project - Same result.
Tried removing installed plugins (only saw Quixel Bridge, removed it just in case)
Checked the logs for my projects, could not see any errors or exit codes that looked like an error or crash.

I think the key is the same persistent address every error: 0x000000000000016a

I’ve seen 1 or 2 posts but no responses for it.

I haven’t started troubleshooting DirectX or drivers yet since the errors appear to be UnrealEditor specific.

Apologies if I’ve missed something while searching, I’m new to Unreal Engine and Game Dev in general.

TIA

One thing to add, it looks like it only happens when I try to play it in the active level editor view port. If I select Standalone game option, it opens in a new window successfully and I can play and control the demo character.
