After upgrading to 2021.3 and Supervisor 2021.03.4 important stuff is broken

What is broken:

My Conbee2 stick disconnects from my Virtualbox VM and I have to change USB ports on my Windows machine to get it recognized again. Thinks this happens every time the host or supervisor is restarted

Device tracking is gone from AsusWRT, the new integration won’t configure and on top of that the companion app does not want to register my mobile as a new device ending up in the following message:

This entity is currently unavailable and is an orphan to a removed, changed or dysfunctional integration or device.

If the entity is no longer in use, you can clean it up by removing it.

I tired to uninstall the app, remove old entities and reinstalling the app without any luck. The other sensors are registered as they should though.

I tried to restore everything from previous backups without seeing any improvement.

Is anyone encountering similar issues?
