I Need Help With My Object Inspector Because I'm An Idiot

So I was making my game and i locked my inspector in place and i accidentally closed it after the fact and now i cant edit anything until i can figure out how to get it back, can anyone give some help?

*or if everything is messed up, can do Window/Layouts/Factory reset.

Thanks, i guess i just didn’t realize that i needed to click my object first before clicking that

Or right click an existing tab and add it back that way. I think it’s one of the reasons Unity might be removing the close x

I like having it, but it’s quite confusing for newcomers to accidentally nuke the inspector while depending on it for learning purposes, and haven’t got used to how the editor works.
