Serviio 1.3.1 - Unexpected Error 500

As of yesterday, Serviio has seized to recognize any of my device. After I reboot the computer, the server appears to recognize the shared devices right away, however, after a couple minutes, it just de-list the devices the list and that panel is blank. After I try restarting the program, I get an "unexpected error (500) check the log". I am not sure what is causing this.
The program shows the server continues to run, but all the devices then disappear after I try to access a couple folders. The only way I can get it to work again is to reboot the pc.
I've attached the program logs for reference. Thanks in advance.
