Loaded a model from local file with 2020 Pro license and didn't work

Got an error that said to save the model as a previous version using the SketchUp viewer app on Windows desktop. Not sure why my 2020 license would require me to save my model as an older version to view in VR, could someone explain that to me - or is that an error message produced as a result of some other bug/glitch?

I tried a couple more times and it finally did load.
