Google Photos and Files Apps on Google Pixel 2 is giving the following error "android.process.media has stopped"
Thanks for this suggestion, I tried several onces that suggested stopping some processes and removing cache but they did not work.

I want to downloads as you suggested, removed some files I recently downloaded, checking the date when the problem started (I did not find goo.google.com files).
Reboot and problem seems to be solved for now!
