This same problem has come up for me while using the June 2022 Feature Update.
I have discovered a work-around:
from the Service, click Get Data, then under Create New Content - Files: click Get, then select your file from the options (Local File, SharePoint, etc), and it will publish with no issue.

Hope this workaround helps you while MS figures out what the problem is.
