Linux Desktop: Authenticator crash on startup: "dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed"

[dbrophy5]

Description

Just installed for the first time on Linux Mint using the deb, downloaded from GitHub releases. Exact mode of crash differs each time it starts up, here is an example though:

Sometimes it crashes immediately, sometimes it freezes with black screen, sometimes it loads the login screen then freezes when I click anything. In any case, it doesn't work at all.

Output of uname -a:
