That migration problem (large wal) is fixed, so I don't think there's a relation with that specific bug. Though, it starts from MigrateV48FrecenciesRunnable. It's crashing on a call to sqlite3_mutex_enter(db->mutex); It's a crash on shutdown, just check the Shutdown Progress aggregation, we're likely not handling properly the database closing under us.

Pretty low volume, let's fix-optional for 62 (tho we'd likely want a patch for uplift depending on complexity).

Only 3 crashes on the 63 branch (nightly and beta) since July, marking as fix-optional for 63.
