Unreal 5.3 Crashing at Game Start

I’m new to Unreal and have been building a VR game. Everything has been fine for months. Then, suddenly, whenever I start my game, it immediately crashes and gives me the “GPU Crashed or D3D Device Removed” error message. Thing is, I haven’t changed or done anything. It was working fine, and then suddenly just stopped working one day. There have been no updates of any sort. No changes of any kind. After it kept happening, I followed through on the “usual” fixes for that error i.e. regedit, updating drivers, all that stuff. No dice. What gives? Why did it just give up the ghost out of the blue like that? Any help would be appreciated it’s been four weeks since I’ve touched my game it’s like I’m not allowed to build it anymore. Here’s the crash log info. I have no idea what any of this stuff means…
