Bluetooth not working on RTL8852be

I've got a wifi/bluetooth combo card. The wifi works perfectly, but I can't seem to get anything to connect to bluetooth. The controller is detected, and it see's bluetooth devices, but won't ever connect.

From everything I've read support for this bluetooth controller should have been added in linux kernal 6.2. Any help would be appreciated.
