I'm new to all this so I have.no clue what it means or what to do any help is appreciated.

Looks like there is something wrong with that homebrew weapon. If it is yours, post a link to it. If it was made by someone else, contact them.

There is also a bug with public homebrew shared via content sharing that may not have been fixed yet. This might be that.
