I posted on both just wanted to make sure I've haven't messed up anything docker end as it was working fine till updated and all fell apart and fresh install wasn't fixing it.
Probably not relevant to the freezing issue, but you need to fix your mapping. You have /mnt listed along with /mnt/user paths. I suggest you read the docker FAQ's on path mapping. A good start would probably be to remove the /mnt that is by itself.
You neglected to post what the host paths were mapped to inside the container, so it's not possible to tell what other issues the duplicate host mapping may be causing.
Anime and Tv shows was added recently because I thought might be the /mnt path causing an issue. Those are the host paths on the container. I just wanted to get how everyone else set up so could eliminate the docker as issue, which hurricanehrndz already mentioned it's Emby itself freezing the system.
