Yeah, could be the update bricked a bad bunch of modulesHmm. Sounds increasingly like a bad batch of camera modules.
But do you have a bricked camera using the native app?Have you tried 'camera PX' app from xda developers? Mine works a charm. Might be worth a shot. No root required.
I need my camera for work and it appears Google is not going to do anything to fix this. It is not a hardware problem, we have 9 Pixel 2 XL phones at work and non of them have a working camera now, 9 phones is not a coincidence it's a flaw in one of the past updates, all 9 do the same thing, hit the camera app, get a black screen, and it just goes back to the home screen. Calling Google is a waste of time, neither front nor back cameras work on any of them. Can not afford to buy 9 new phones and can not sell them like this for even close to what a used Pixel 2 XL was worth before this camera crap started. If I need to replace them it sure as hell will not be with anything Google sells.
[Please be careful with the language]OK, my Pixel 2XL was fine yesterday, had problems this morning but DID manage to take 3 pics but now I have the same problem you had, did you ever get it working?
I take pics probly every day, hate to think I have to get a new phone just cuz the camera mysteriously stopped working! [Mod redacted]

We were away from home today, I followed the google assistant instructions trying to get it working but stopped when it offered to call Google, will try that tomorrow. From what I've been reading though it's going to be a waste of time, they'll want me to reset the phone etc etc and no one has gotten it working again.
