cant use editor

I cant use the editor mode anymore for some reason. I was playing around with things in the edit tab and now i cant see anything besides my grid. Please help

I was able ti fix the problem recently and i figured i would elaborate on what happened and show how to fix it. Now for elaboration. I simply couldnt see any blocks i had placed and focusing in on them didnt help. If this has happened to u then my cundulences. But there is a extremly easy way to fix this.

1.) Go to the top right corner and click on layers
2.) Click on the bar that says “Everything”
3.) Well, thats about it. But i apretiate all the help.
