Completed Download transfer is corrupted

Sonarr version (exact version):
OS: Windows 11 Home
Debug logs:
Description of issue:

Sonarr with Jellyfin using Jackett. After download completes with qBit, the file is moved to shows folder and ends up corrupted. Not all the shows do this, but it seems most are. This is a sudden and new problem that arose after my pc was off for a week. Updating to V4 did not solve the issue.

The server is all ran on my personal computer, ran on a local SSD, no networking involved.

You can easily search for traces related to this download by searching “Mushoku”

Manually dragging the file into the jellyfin folder, and refreshing naturally brings it in fine.

I read through the end of the logs but I am not familiar enough to see what is going wrong.

Can anyone help?
