Studio One, No Playback AT ALL, windows audio

Please Help, I use my Yamaha keyboard coected through USB and when I play I can see that the program picks up the sound as the blue bars on the left bounce, and records the midi when I press record. Also, I use windows audio, and a pair of USB headphones, and speakers available. I've reinstalled the sound sets, but also there is no folder for the "Instrument Library" I don't know if that has something to do with it. Sound works on other apps and sites like youtube, I'm using windows 10. Also, I have a Scarlett 2i2 coected but not selected in studio one. It wasn't always like this, I've also deleted all .setting files and let Studio One rebuild them, didn't work. How can I get the sound back?

Edit: Loops don't play either but I can see bars bouncing, and some of them have "crunching" noise in the speakers.
