I have a MyQ Garage Door system and the unit just started beeping, roughly every minute

Wondering if anyone out there might have experience in knowing what's wrong and what I need to do to stop it. Owned it for 2 years, but I didn't do the installation myself.

Also if it needs repair or something, what might it cost me and how difficult would it be to do myself? Thanks in advance, I know someone here always has experience I lack lol
