SevenZipNativeInitializationException: Failed to load 7z-JBinding: no 7-Zip-JBinding in java.library.path
JNA Warning: IOException removing temporary files: JNA temporary directory '/volume1/@appstore/filebot/data/temp' is not writable
Input:
Delete all folders in /volume1/@appstore/filebot/data/* then.
You probably ran filebot as root for the first time. So you initialized everything as root with root permissions, and now that you run as normal user it doesn't have permission to access it's own cache/temp/etc files.
