Alright, I'm aware of the Rift S black screen issues but this is the first time it happened to me, but not exactly in the way I've heard it happen to others.
So I was on the Oculus PTC and had 1.39 installed, ever since I bought this unit back in May 25 it was working flawlessly except for the common static flash issue (which I have already submitted a ticket for.) 1.39 worked for me and I was really happy with the tracking of it, but recently after I put my headset on, around 30 or so minutes later while playing the screen would shut down and I'd look at my monitor and the Oculus Software has closed and is restarting on its own. It's weird, I don't think it's a hardware issue as that wouldn't cause the Software to force close and restart.. Shouldn't it give me a message like "Display port not working" or "USB Device not recognized"? My Rift S is still Green checks and my controllers are all full batteries, no error message occurs when this happens.
I tried the following troubleshooting steps:
1) Unplugged the headset from both PC side and HMD side, USB 3.0 first then waiting for 5-10 seconds until plugging into the Displayport.
2 ) I opted out of PTC and reinstalled 1.38 and rebooted my PC, I also opted out of the Steam VR Beta. I also tried plugging it into another USB 3.0 port and it worked for 3 hours until the headset tracking stopped (static image while moving my head) and the display shut down again, with the Oculus Software restarting itself again.
Repairing Oculus Software didn't fix it but I was able to replicate the problem 100% of the time.
So I play in a dark room with a lit lamp, it has worked for me ever since the Rift S launched. While testing out the Rift S again, I looked at a corner of my room with no light on it and my Rift S stopped tracking (expected) and it also crashed the software, turning off my display. I tried playing with the room light ON and there was no crashes wherever I look. I turned the lights off again and just used the lamp and it KEEPS crashing when looking at that one corner in my room with no lights. I'm pretty sure it's a software issue at this point. I have cleaned the Camera lenses and everything else. The last resort I'm currently doing right now is deleting every single Oculus file and folder in Safe Mode and uninstalling the software itself.
I don't know if anyone else experienced this issue on their Rift S, but it's really weird that it would start doing this all of a sudden when it worked perfectly literally a few hours before the issue started appearing. No visible damage or warping on the cable, and tugging on the cable doesn't cause the black screen to happen so I don't think it's loose. The 1.39 update also worked flawlessly up until this point so I don't think there was any changes to the Oculus Software itself either..
