@Ida_ I didn't try connecting to any other Bluetooth devices. I just know it didn't want to connect to my headphones. Which I found funny considering they were the matching Fairphone brand lol

As for other ROMs, this is not a problem. I flashed to the stock Android 13 FPOS before I ran the UBPorts installer appimage.

So it's not an issue of having the wrong base android
