Syslog wisej-servcer.lic io error and Object reference not found or set to an instance of an object.

System: Debian 11, WiseJ 3.1.2, Dotnet 6.0.404

While reviewing our syslog we are noticing the following error every 30 seconds roughly.

Mar 19 10:29:01 wisej1 dotnet: onemci Error: 0 :
Mar 19 10:29:01 wisej1 dotnet: System.IO.IOException: The file ‘/opt/[our_app]/wisej-server.lic’ already exists.
Mar 19 10:29:01 wisej1 dotnet: onemci Information: 0 :
Mar 19 10:29:01 wisej1 dotnet: RefreshAll:

Not sure if the two are related. We are also attaching a screenshot of an error that appears after the system is in use for a few hours. The message box shows before a user does any interaction such as clicking the login button and there is no code in the load event.  If we restart the wisej application using systemctl the “Object reference not found or set to an instance of an object” error goes away for a little while but then returns.
