New Package ID Error

See screenshot. I’ve been naming my packages like this for 10+ years with no issues. First time I’m getting an error. Any fix? This is with build 3730.

Update: seems like there’s a bug in Mac OS or somewhere else. When copying the package ID from the android dashboard, it adds a * symbol to the end for some reason (invisible when you paste it). I manually typed out the package ID from scratch and it worked.
