Just to follow this up, in my vrserver.txt log I was seeing a lot of "[Info] - vrlink: sendto error 10055" events on SteamVR 2.7.2 beta and eventually:

On SteamVR 2.6.2 all the "sendto error 10055"'s seem to have gone away. I'll see if things are stable tonight.

I( have this exact same issue since two days ago. No idea what makes it happen ive tried everything from reinstalling steamvr and using beta version, to reinstalling older gpu drivers after trying the most recent ones too... ive even factory reset my Quest 3 but nothing worked. Please help, my hedset is literally unusable rn

Is there any update on this matter? I started experiencing this too. I opened a ticket some days ago and I am talking with support because I had some other issue while playing Half-Life: Alyx and after some tries I'm now stuck with this error.

Hey everybody - have a look at the solution/workaround Meta suggested here. It worked for me.

For those who experience this issue after a short period of normal connection, my solution is to reduce the video transmission bandwidth: After entering VR, go to the SteamVR menu and adjust the maximum transmission bandwidth, uncheck the auto option. I set my bandwidth to 50mbps, and the issue has not occurred since.

This did the trick for me as well <3

Seems like turning Hardware Accelerated GPU scheduling off resolved the issue for me
