@Alex_Franco - you might try clearing the prints using the appimage from this post: [SOLVED] Fingerprint scanner compatibility with linux (ubuntu, fedora, etc) - #214 by Devyn_Cairns
I had used the python script successfully in the past, but I did have issues with it one time, and the appimage worked. It may be worth a try before reinstalling. I suspect that you have enrolled prints left over from your windows installation. Good luck!
