Hello, it's my first time in this site so feel free to correct me. I also have a same issue, but after some digging through the files, I relocate my storage. Go to Data and Storage-> Storage location. It should prompt you to relocate mihon's data.

It doesn't work if that title name is really (really) long. I have a manga that has long name, even if not count the path characters, it already exceed 300 chars.

I had this error for months popping up, and I had no idea of reasons. Just assume of bug which would be fixed eventually.

Tested. Had 20 chapters from different sites in queue when I discovered thus tread.

Tried:

• shuffling which site gets to download first. Nothing downloads.
• Shuffling chapters from different manga's. Nothing downloads.
• Forcing specific chapter to load first didn't had any effect.
• Started randomly deleting chapters, and it worked after one long title was deleted from queue for download. All other chapters from different titles and even sites started loading.

• Path for library isn't too long for me - /storage/emulated/0/Backup/Mihon
• CBZ compression in use. As a side note, this exact issue seems to cause another one - after exiting application when in this state, on re-opening Index of downloaded chapters might be either empty or partially empty, which forces me to "Invalidate download index" around once per 2 days.

What I can add, it seems adding title which isn't written with Latin causes issue more often (I ASSUME it might lead to non Latin letters recognised as symbols, when encoded as ANSI/UTF, and it makes such paths even longer as each symbol gets encoded by worker process suring update?)

It might be worth considering shortening long titles folder/chapter file names like it was done in FAT32 file system, or other workarounds.

yeah, I think the best solution to fix is allow user to custom their folders/files name. timestamp for example. Because when download, it also include metadata file which already have title name/media information... so I don't think it necessary to have real title name as filenames (or maybe for easy to explore via file manager but it doesn't matter for me...)
