Runtime Error While Executing Python Code

[Stevenj279]

This evening when I opened QGIS' "Settings", "Options" to check the "Rendering" settings, I didn't make any changes and then clicked on"OK" to exit. The window closed and the error message below immediately popped up. Restarting QGIS and/or rebooting the PC has no effect - This error is constant. Of note is that I've been using QGIS for over a year or two, and this was the first time I'd opened the Settings - Options tabs. I'm assuming (hoping) that this is a minor bug and that it is not having any effects on my GIS projects in the background that I'm not aware of. Error message follows:

An error has occurred while executing Python code:

Please try with clean profile and no 3rd party plugins installed.

This seems to be a plugin error entirely.

Closing for lack of feedback.
