I was able to get past the crash-on-launch to make some of the settings changes (disabled favicon download, I don't use RSS or search plugins) suggested on #9667 by launching qbittorrent-nox and removing all the the torrents. Then the crashes stopped. (It would have been helpful to have that in #9667 because it's super hard to figure out how to adjust the settings in a program that crashes the moment you launch it. :) )
