Fedora 36, GNOME, Fopnu 1.57. Trying to share huge amount of small files, about 1 MB. Overall 460,000 files.

Hashing seems OK. After hashing Fopnu dissapeared from memory with no notifications or errors. Where to dig?

If it's not too inconvenient you can always create a zip, rar or tar file.

RAM issue probably?

Tried to replicate with 655 771 files (868MB (1,42GB on disk)), once everything was hashed RAM usage by fopnu was a bit over 8GB,
restarting it lowered RAM usage to a bit over 6GB, but no crashes.
