Getting "Error: Can't convert 9 to proper M credential Type" randomly for all my dataflow refreshes

[csmith_enpro]

Like the title says, I woke up this morning and all of a sudden I'm receiving this error: "Error: Can't convert 9 to proper M credential Type". I have no idea what it means, I'm even still able to create a new dataflow no problem, but it won't refresh. Google has no answers for this either. This is a new error for me, has anyone encountered it before?

I am having the same issue since Friday. Same error.

Whe I download the error report and go into the entity in the dataflow, it lets me refresh one by one, but it is not refreshing the whole dataflow.

You too?! I'm so confused by this, I wonder if it's something on Microsoft's end. That's quite the coincidence
