New to Mautic and cannot edit email with builder

Your software
My Mautic version is: 7.0
My PHP version is: 8.3.31
My Database type and version is: 11.8.3-MariaDB

Your problem
My problem is: I cannot edit in Builder

These errors are showing in the log:

None

Steps I have tried to fix the problem:

Cleared cache and changed browser from Firefox to Chrome

I can open the templates in Builder but cannot change anything on the page. I can if I go to the code editor. Is this how it is supposed to work?

I am very new to Mautic and using it for the first time.

have you installed Composer?

You need to double click the elements, or click on the right side on the + icon to have the available blocks shown.
