So we can investigate that and follow up with you please turn on 'Enable Logging' in PokerTracker 4 via 'Configure -> Options' and then restart PokerTracker 4. Next reproduce the crash and then grab your log file and attach that to a
Support Ticket:
\Users\{Mac Login}\Library\Application Support\PokerTracker 4\Logs\PokerTracker4.logOne thing to note is that every time you close/restart PokerTracker 4 it will begin a new log so you'll want to save/send that PokerTracker4.log file before restarting PokerTracker 4 again. In the meantime you can try reverting to PokerTracker v4.18.3
here if that was the version you updated from. Alternatively you could try creating a
new temporary database.
