I get this error when I try to toggle write\_ on “blockMesh”

I am running blueCFD on windows10. How can I fix the problem?

I used one of the recommendations here: [blueCFD-Core Installation Issue](https://discourse.ladybug.tools/t/bluecfd-core-installation-issue/5278). If i remember correctly it was because of a blueCFD version mismatch.
