Microsoft Office on new computer/M1 architecture

I've just migrated my old Intel laptop "brain" over to my new Mac Studio (M1-max). Now my microsoft programs (excel, powerpoint and word) on the Studio do not run. After they get the license information from my keychain, I get the following message: "There was a problem with Microsoft PowerPoint and we apologize ..." If I click on the "More Information" button, I get the text below (top few lines only). I have deleted the apps, as well as the recommended files to delete in the ~/Library directory, and re-installed from the App store. I have the "Open using Rosetta" box unchecked in the application information -- but it doesn't work if checked also. I still get the same messages. Anyone seen this before, or have any ideas how to fix?
