I logged out of a session while Thunderbird was running in the background.

Thanks. Such a crash is sort of expected as Thunderbird will crash after timeout on shutdown hangs (via RunWatchdog), which I think is likely to happen when doing what you describe. Similar to bug 1624171

Not actionable. Try Thunderbird 91.
