Switch pro controller bluetooth connecting, but not working?

I enjoy using my switch pro controller to play steam and emulated games on PC (windows 10), and it was working great until recently. Computer says it is connected and paired properly as a 'Lic Pro Controller', which is what is has said before. However, usually the connection lights on the controller will stop blinking, and have just one lit. Recently, it has continued to flash, and hasn't stopped blinking for 5 minutes. I think it has something to do with the controller. Anyone have a solution? I have tried:

Putting in new batteries

Updating bluetooth drivers

Removing the device, and re-pairing it with Sync button

It does work properly when connected to a Switch. I don't think a windows update broke it because I hadn't updated my computer until it stopped working. Any ideas?
