radiant::radiant_viewer() - cannot create dir 'C:\Users\ejohn\OneDrive??????.radiant.sessions', reason 'Invalid argument'*

I am trying to work with Radiane and R. There is a .rds file that my instructor created from one of his research projects. Others in my MBA cohort are able to open it, but when I try to start R, the below text is what I get. the default data is present in R, but when I try to load the .rds file, radiant can't open the file. I believe that the attempt to create a directory on onedrive is the problem, but I don't know how to fix it. My default browser is Chrome, but it also failed when I set my default to Edge.

starting radiant in the default browser ...

Use radiant::radiant_viewer() in Rstudio to open radiant in the Rstudio viewer
or radiant::radiant_window() in Rstudio to open radiant in an Rstudio window
