Description of the issue: Give a a clear and concise description of what the issue is.
files dropped from fmd2 into the input folder are recognized and formatted correctly. Manga Tagger renames them then displays this message:

2024-05-09 17:15:39,410 | Thread-1 140234709678904 | MangaTaggerLib.task_queue.SeriesHandler | INFO - Moved event for "/downloads/Berserk/Vol. 03 Ch. 000.06 - The Guardians of Desire (4) (LQ).cbz" will be added to the queue

After that nothing happens. Hours go by and the file is never tagged, and never moved to the destination folder.
If I restart it sees the renamed files on the restart and indicastes the format is wrong, but it is in the format that Manga Tagger renamed it to, so not sure why it doesn't recognize the file it created, but maybe that is part of the problem.
