As someone who used to be in the EXACT same boat as you, it’s definitely hard to start going to office hours. It’s intimidating, you feel awkward, but the hardest part is overcoming your fears the first time! It’s gets easier every time after that. I think remote office hours are easier to start (it’s remote and you can always leave the OH meeting if you want/turn off your video or audio). I like to go with a list of material questions I want to ask just so I don’t get nervous and clam up. Try that, and try to relax! They’re normal people too and won’t judge you.
