Error 567812 on desktop 2025

I'm just getting started with desktop deluxe 2025.  Saving my file for the second time and all subsequent attempts produces this error claiming that it's a read only directory.  Saving to another directory produces the same error.  Creating a test file seems to want to go to onedrive rather than the C drive.  The file was originatly created on the C drive.  Is it possible that something changed to redirect saves to one drive?  If so, how do I change that behavior
