Why did both cameras stop working?!

Okay, so my phone was working amazing after changing the screen. Everything was mint for about 2 weeks. I plugged it into my.pc to update to ios 17.whatver and now...now neither camera works. Its a 128gb iphone 11 and like i said it was totally fine until the update and now nothing. Ive tried every option i found on other simaler threads(force restart,update,chwck the hardware) to no avail
