I have researched this topic and cannot find a way to stop Steam VR from stopping. Playing on Half-Life Alyx and other games. Out of nowhere the game stops and teh PC displays a message that there is a critical error and I need to restart Steam VR. No other mention of what the error is, just that it is critical! Always at random times, maybe 1 min, maybe 45 mins? Running Windows 10, 16gig ram, RTX 2070, Ryzen 7 3700, latest Geforce and other drivers. I am using Oculus brand link cable directly to USB-C port on motherboard. I have tried multiple reboots, launching every different way I can think of. Sometimes I can restart VR and get back to game, but most times Steam VR restarts and I see game on PC monitor but black in headset. I am tired of constantly reloading the game and saving constantly so I don't lose my progress. Please let me know if anyone has any suggestions!!
