Access to the path User.zip' is denied

Hi,

Yet again, I was using Power BI Desktop fine, closed the application, then remembered I needed to make one more amendment and now I cannot open Power BI Desktop. I receive the below message...

Feedback Type:

Error Message:

I've tried renaming the temp file, but that didn't work. Reinstalling the Desktop version doesn't resolve it.

Any help appreciated, as now I cannot access it.

Thanks,
