qbittorrent config becomes an empty file, moving all torrents into config

[Eagleman7]

Hello,

Yesterday I've seen it for a second time where I restart the VM where qbittorrentvpn is running. It then starts qbittorrentvpn however the config file is somehow empty:

It then load back all torrent:

Untill it decides to move all torrents to /config because the config file is empty, so all config is gone:

It then fills the VM untill the disk becomes full:

I've stored my qbittorrent data folder on disk in the VM at /opt/qbittorrentvpn.

What are reasons the config file could become empty? Is there a way to stop this from happening or detecting it?

Thanks!
