Nintendo Switch pro controllers and emulators issues

I have 2 Nintendo Switch Pro controllers I used them on emulators a little while back and they worked on the emulators I used just fine.
Then again with in the last few days and they worked on the emulators I have been using just fine.
but today one controller went completely hay wire it started out with just controller input it was going through the inputs and changing the buttons.
Then it started kicking me out of emulators , kicking me out of stuff thats not even emulators , kicking me out of web pages , putting me in to web pages.
The other controller just doesnt work on emulators.
The blue light doesnt come on either controller.
So I tried connecting each one , one at at time to the windows 10 blue tooth but neither one will connect to the windows 10 blue tooth.
Last time I used my controllers for emulators I used them with the windows 10 blue tooth.
but this time i used my controllers for emulators I used 10 foot USB cords and plugged them in to the pc.
