Lost Bluetooth (mini 2012, Monterey, 1.5)

Have a Mac mini i7 2012 (16GB, 1TB SSD) i've been running Monterey on via OCLP very successfully for a couple of years now. Yesterday when prompted I upgraded OCP to 1.5, the machine is running the latest update to Monterey. Across successive reboots, reinstalling OCLP, redoing the root patch which on this machine I believe is just for the HD 4000 graphics, etc., Bluetooth is dead. It's switched off in the control panel and I cannot toggle it back on. My Bluetooth mouse is a paperweight. Help?
