The Project Browser says there's a "#" in the project name, even when there isn't.

Whenever I try to create a new project an error comes up saying, “Path may not contain the following characters: #”. There’s no # in anything I type. I just type “Project”. Is there anything I can do about this?

Not sure if real problem or just shameless promotion of some hashtag.

It clearly says it’s in the path, not in the project name.
Change the folder.

This is the correct response. You’ll need to change the file path to a folder that does not include a special character.

Have a great day
