MFA Error 50076 using Power Platform Dataflows

Question

I am having an issue that I believe is due to the new number matching MFA that Microsoft rolled out, but I can't seem to find anyone else having the same issue. I use Dataflows many many times per day and have never had an issue. My password expired yesterday and after resetting it, I'm now given a 2 digit code on my screen that I have to enter into my Msft Authenticator App on my phone. This is happening with Teams, Excel, Outlook, OneDrive, and everything else as I re-authenticated after updating my password. I read about it and it seems Msft rolled this out on May 8th and you cannot opt out.

It's working fine except for Dataflows in PBI Desktop and Dataflows in Excel where it prompts for password as normal but then fails to pop up the box with the 2 digit number. Below is the error message I am receiving and our IT has no idea what to do about it or how to resolve. Any help would be extremely appreciated. My reports are now broken and I am in a pinch to figure this out urgently.

Have IT check the Azure Sign in Logs. It will probably show that your dataflow is failing at the MFA requirement. I would suggest switching the account used for that to a service account that doesnt require MFA and test it out.
