'Ignoring asset refresh' warnings in console

i am on 2019.3f1, whenever i recompile my scripts i get a ton of these warnings:

 

I am also getting these warnings after updating from 2019.1.6f1 to 2019.3.0f6...
Anyone got any further info on this?

 

Attempting to export my assets also caused multiple ArgumentException: Invalid path exceptions and prevented export.

Stacktrace:

To resolve I had to select individual assets and attempt to export. If I didn't receive an exception I cancelled and tried the next asset. I eventually identified the cause(?) as the scenes within the Assets/Oculus/VR/scenes and Assets/Oculus/VR/Editor/scenes folders.
I attempted to reimport these but no luck so I deleted these folders and could now export my assets. This also resolved the initial: Warning related to Ignoring asset refresh of <..>

Problem resolved but would still like some feedback from a mod perhaps as to what has caused this.....
