It helps a great deal.
You have permission problems on two shared folders showing up immediately.

Here’s how to set that.
Are you using the Synology-supplied shared folders? ( I think you are )
If so, make new ones and move your media files to them then set Plex to look in the new shared folders.
DSM 7 , in anticipation of using VideoStation, PhotoStation, and AudioStation, claim permissions of those shared folders and REMOVE Plex’s permissions almost as soon as you add them.
It’s been a constant conflict with those Synology apps and their insistence on not sharing the media.
