Avoid using spaces, accented letters or special symbols in the
folder names of the path where you are storing the project.
Only a-z, 0-9, “_” and “-” are safe for naming things.

After you remove the spaces in the lovecraft folder name and the one
just inside it which also seems to have a space, the save should work
unless there are other issues.

I’m having the same issue, not allowing me to save. I tried changing the name but nothing is working.
