How do I get my landscape editor and bsp toolbar in my project?

As you can see from the photos provided there is no landscape editor to use for my project. For some reason it’s not an option for me anymore. I didn’t do anything to get rid of it and I don’t know how to get it back. Can someone help because this is very annoying. I made the landscape and I cant even edit it anymore. It’s been like this for days and at first it was being launched in a separate window from my project. 4.11.2 I believe

Here is the problem!

There is no landscape editor window

Nevermind I figured it out
