I had the same problem.

I’m using Rhino 7.0.

However, after installing blueCFD-Core 2020-1 and using Butterfly, I had the same problem as you on Blockmesh.

However, I completely deleted blueCFD-Core 2020 (down to the folder) and reinstalled blueCFD-Core 2017-2 to run Butterfly and the issue was resolved.

Please note.
