Windows 10: Bluetooth Driver Adapter Code 31 Error - Techkey Bluetooth 5.0 Adapter

I am having an issue loading the driver for Techkey Bluetooth 5.0 Adapter on Windows 11 Home Version 23H2. I receive a Code 31 error. I have tried several other workarounds that have been described in other Microsoft forums. So far, the only solution that has worked temporarily is to perform a restore point. However, this does not permanently fix the issue as the computer updates, and now I can't go back to that restore point.

Bluetooth USB adapter recommendation

Thanks Denis for your input...I remembered I had another Bluetooth USB Adapter so I tried that. That adapter worked perfectly with the controller. I put the original adapter back in. It worked a lot better than yesterday but not as good as the other Bluetooth USB Adapter. I then saw your post. The computer is almost 5 years old now. I try to check the Device Manager every month or two. I can't even remember the last time I saw a problem there. However, you were right. There was a error there. The error was something like "USB Device not recognized". I found the solution was to first figure out what was causing the error. I then remembered I had bought a new Logitech C920s Pro webcam a couple months ago. I unplugged it and plugged it back in. The error in the Device Manager was now gone. I am still not 100% sure if the problem is completely fixed. I will have to watch things for a few more weeks to make sure.
