I think somebody's typo let new version crash when run FEM WB.

Please fix this problem.

When using "Create mesh from shape by Netgen" command, I got failure. But different than yours.
So, the issue has not been recovered completely.
But my OP's title is about "startup", so we'd better talk it in new thread.

I have found the problem. Due to netgen version.

Please use netgen old version. e.g 6.2.1808

DON'T USE NETGEN VERION 6.2.2004. THIS VERSION WILL CRASH FEM WB !!!
