On 6.9.2 I was passing through my onboard Bluetooth Controller on my Asus B550 Strix-E which was working fine, however since updating to 6.10.0-RC1 I am no longer able to do. It works fine in BM on Windows 10 but throws up a Code 10 in a Windows 10 VM and doesn't let me enable Bluetooth in a PopOS VM.
It's picked up as "Intel Corp. (8087:0029)" when trying to passthrough and is twinned with the onboard WiFi 6 (which I have disabled as I don't use it).
All other settings are the same as they were before updating. Diagnostics attached.
