It worked! My PC has B550 mobo (ASRock B550 Phantom-itx) and had the problem that the 'Rift Audio' device stops after starting WebRTC screen share inside Unity app. Also sometimes tracking of Touch / Rift stops.
I've done updating BIOS, driver, changing app version,... nothing worked. But the problem just disappeared after I switched PCIe to Gen3 on BIOS!
For ASRock BIOS: BIOS > Advanced > AMD PBS > PCIe x16 Bus Interface (Auto/Gen1/Gen2/**Gen3**/Gen4)
Thank you!

Glad I could help! 🙂
Meanwhile AMD confirmed the issue and is looking into it: https://www.reddit.com/r/Amd/comments/lnmet0/an_update_on_usb_connectivity_with_500_series/

Update: AGESA 1.2.0.2 is supposed to be released in 04/21 and should fix the issues.

My God, I don't want to get excited just yet as I've tried a million fixes with no success but I have a B550 board. That would be incredible if this fixes my issues. Does anyone know if the AGESA 1.2.0.1 fixed this issue? If not, I'll wait for 1.2.0.2 and use the forced PCIe 3.0 workaround in the meantime. Will update if this worked for me later when I'm home from work.

No, this issue is addressed with 1.2.0.2, .1 was released back in February when AMD was still investigating.
Fingers crossed the PCIe 3.0 workaround helps you as much as it helped me.

Try this.
Last "upgrade" blacklisted tons of USB 3.0 drivers/controllers. Mental why they would that.
The solution is to revert back to earlier software and firmware.
All in here (credit to another poster, not my work)..

Change (dot) in . and paste link in browser."
Works for loads of people with the same problem. Try it!

Ah okay. It actually appears there was a "Patch A" released for 1.2.0.1 a week ago for some boards (unfortunately mine is not one of them.) Unsure if this patch has fixed this issue for some people, I was reading a bit about it here: https://wccftech.com/amd-agesa-1-2-0-1-patch-a-bios-firmware-x570-b550-motherboards-fixes-ryzen-5000....
Either way, I'll be trying the PCIe 3.0 workaround right now. Just switched it from auto to gen3. Will update if this worked for me after (hopefully) a few hours of testing.

I believe this was one of the earlier fixes I tried some time ago, can't remember for sure. If this PCIe workaround doesn't work, I'll be sure to give that another try. Thank you!
