Vive 2 suddenly not working

Hi, new to both VR and FS here and would appreciate some help: I’ve played on a Vive 2 without issue for a few days. Yesterday, I started fiddling with the VR graphic options within the game. It was fine for a couple hours, but after I raised the resolution too high, the headset now drops drastically in framerate even on default settings immediately upon starting the game (even before I activate VR mode), as in, over 100 on the Steam performance graph. Unless I restart my pc, the headset remains very glitchy with strange pixelated rays all over the place within Steam VR Home. I’ve reset all graphic options both in-game and in Steam settings to default, and tried re-installing everything (Steam VR, USB reset, headset reset) several times. Occasionally, I can get it to act normally again in a VR flight, but as soon as I exit VR mode, it’s back to glitching. Am I missing an important setting somewhere globally? Please help!
