Error running blockMesh.C at line 408.

[RFBomb]

Installed OpenFoam8 on Windows 10 following the guide. Whenever I run blockMesh I get an error. Error log posted below.

I was following this tutorial, using all those files she linked to. https://www.youtube.com/watch?v=oc4V79F78AQ

From the error message, it appears to be be an issue with From function int main(int, char**) in file blockMesh.C at line 408.
