Have you updated iTunes?

Does it show up in iTunes?

Do you launch iTunes before trying to access the iPhone as storage?

Are you getting prompts on your phone to trust the computer?
yes

wifi sync only, when ejected then plug in the phone it doesnt show up

yes

no trust prompt

edit: wifi sync not working anymore after reinstalling itunes :(

edit 2: i think the issue is the phone since it also doesn't work on another pc, but that pc works with a different iphone.

should mention that my phone doesn't charge with usb from pc either.

The only other things I can think of at the moment.
  • Blow put lightning connector with canned air.
  • Disable USB Restricted Mode (although that should only turn on when locked an hour)
  • Try an official Apple cable
  • Factory reset iPhone. To see if it’ll connect in a vanilla state. Obviously have a full iCloud backup first. To restore from after your test.
  • Try connecting iPhone to a USB accessory. Such as a flash drive.
