qBittorrent v2.8.5 bug at win 7 64bit?

[gms]

After changing the label of a large downloading torrent file (with append label checked) the qBittorrent practical stoped working. I got no message at all but downloads become stalled or got the checking status. Also no new download could start, all become stalled. Restarting the qBittorrent some of the unfinished torrents started working but after 3-4 seconds they are stopped again. I reinstalled the 2.8.5 again with no luck. I tried the 2.8.4 and got the same problem.

I installed the 2.7.3 and everything was fine. It completed the checking and all downloads started to work normally. After that I installed again 2.8.5 and it was fine.
It looks the 2.7.3 is the most stable version. It worked fine with no I/O errors and it did the job again. At least at win 7 64bit.
