Microsoft Forms - new error message preventing refresh

Question

Yesterday I set up a workaround to load a long running MS form into Power BI (as exporting a spreadsheet each month is really annoying!)

I used this video by Bielite https://bielite.com/blog/microsoft-forms-data-power-bi/ And it worked perfectly....BUT this morning when I hit refresh I got this error message:

"The WWW-Authenticate header doesn't contain a valid authorization URI. Header value: 'Bearer'."

and it wont let me authenticate with my credentials.

If I copy and paste the URL it is using into my browser, it simply downloads the excel file so the URL is correct.

Any help gratefully received (as I am a relative beginner compared to most!)

I'm also having this issue. Very frustrating since we just implemented a new tool that relies on the forms API.
