TypeError: Cannot read properties of undefined (reading 'tokenType')

I'm having the same problem.  After this error occurrs, I then see numerous other 403 errors (see errors below). 

All of this is recent and impacting both embedded PowerBI reports.  An updates on when this will be resolved and/or what we can do to resolve it?

.... a couple dozen more appear like the ones above with different model numbers.
