Get this pop up error when I try and export step files:

Does it show OK in the 3D viewer ? if not that might give you additional hints to what is the problem . . . but it might be related to these lines . . .

Yes, shows up totally fine in 3D View. it is a bit of a funky shape but 3D viewer has no issue with it.

BUMP (hope that’s not a bannable offence?)

I recommend you report a bug on gitlab with your board attached

Probably you already fixed this, but I had the same problem.
I had a non-contiguous board outline, apparently.
I fixed it by selecting each segment and moving the endpoint
until it snapped to the adjacent one.

You can also run DRC and it will point out exactly where the outline is discontinuous.
