.NET framework error

[radiouser]

I'm getting the following error about once a week. RadioDJ is in AutoDJ mode and automated. Nothing needs to be done by the user to get the error to show up. It appears by itself.

Computer is running Windows 7 Pro SP1 and .NET framework version 4.7.1.

Please ask for more details. I'm not sure what is needed to solve this. You can find the error message below.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Does this error appeared since beginning, or it appeared after some time of using rdj?
As a workaround in rdj options-plugins-search plugin options uncheck real time refresh

[radiouser]

It was a clean install and it had been running around the clock for a few days when the error appeared for the first time. After that the machine was rebooted and again it took a few days to reappear. Real time refresh is now disabled.
