Chiming in here as I also have the same problem.
Windows 11, TP-Link UB5A dongle (although the same thing was happening with built in bluetooth) I would connect my Satisfyer device to windows, it would connect in Intiface, work for a random amount of time (I counted 30 seconds on one of the attempts) then stop working completely, even with no errors in logs and device still saying it is connected. If I stopped the Intiface engine the Satisfyer device would “disconnect” from windows and Intiface then go into pairing mode. Turning the Intiface engine on again and scanning to reconnect the device would make it work again for a short time before it would just stop working again.
