Running the 10.5.2-arm docker image with Anime plugin 7.0.0, using AniList causes crashes whenever a library is scanned, giving the logs below. Disabling AniList seems to solve the issue.

after letting it run awhile, it looks like I'm getting this issue from RegExes elsewhere too. For what it's worth, other series with spaces in their names worked fine.

For what it's worth, my logs are also getting spammed hard from jellyfin/jellyfin#2471 - hopefully that turns out to be the root cause of the issue, since I'm also getting crashes without the above error

reverting to 10.4.3 with plugin v4 seems to have worked as a temporary resolution. It feels like a use-after-free issue, but I'm not familiar enough with C# diagnostics to be able to track that down.
