Plex can't find my media anymore

Server Version#: 1.18.1.1973

Hi, about a week ago i updated my PMS to 1.18.1.1973 and alot ( but not all) of my media became “unavailable”
what i have done:
made the right permissions for my shared folders
downgraded PMS to 1.16… and 1.3… and back to 1.18.1.1973
deleted both plex user and plex shared folder and reinstalled plex
it seems to only be the newest media it cant find

can anyone look at my logs to see if there could be an answer
