Your best bet is to downgrade for now. The plugin author has a terminal command posted on their GitHub plugin page that I used. Here’s a link to it. https://github.com/chodeus/folder.view3/releases/tag/v2026.09.17
On the latest version 26.1-01, I'm getting an error 'Could not load certificate store location from /usr/local/share/nzbget/cacert.pem.' I verified through the console that the location with the file exists. Currently, I pinned the container to version 26.0-01 until I can figure out what's going on.
