qBitTorrent not updating

Currently the qBitTorrnet version on the ReadyNAS App store is v3.1.10, which is ~2 years old now and isn't compatible with programs such as Sonarr.

I've tried Super_Poussin's update on his Dropbox, but it doesn't seem to update properly anymore. When I try to simply upload it in the ReadyNAS App store page, it says that it can't turn on the app and to contact the developer.

I tweeted at Super Poussin, however he doesn't seem to be active on Twitter.

I've also tried using the instructions to install it manually via command line, but produces the error seen in the above tweet:

Is there any way to get an updated version of qBitTorrent that will work with Sonarr? According to this Reddit comment, I'd need at least v3.2.4, though I'd like the most up-to-date version if possible.
