fxsound doesn't recognize my headphones

Good morning, previously fxsound was recognizing my Bluetooth headphones. However, at a random moment it simply stopped recognizing my headphones and they don’t even appear in the fxsound list. Of course, I can use them normally without fxsound, but there are apps that also don’t recognize the headphones, they only recognize fxsound. Nothing shows up in the sound mixer regarding my headphones, and I don’t know if the problem is with the Bluetooth, the PC, or fxsound. Can anyone help?
