Every time I play I get " An error has occurred in the following application. (CE-34878-0) Four Kings Casino and Slots" as quick as 30 seconds, up to 15 minutes, the longest I have been able to play. Any chips bet (on the table games) are lost.
Have you tried restarting your PS4? If that didn't work, remove and reinstall the Four Kings Casino and Slots application.
Best to do a full power cycle of the PS4, dont reboot via standby mode, do a full power down and turn back on.
