I have no way to test Aspen so I can only assume based on how other weaver theme would work.
In Appearance > Weaver Admin > Main options > Header > there would be a section Custom Logo with a Hide option.
But normally in Customize > Admin Options > Site Identity, you should have the option to remove the site logo.
As this is normally a WordPress setting, you may want to try and switch to another theme and see if you can remove it there,
Worst comes the worst, we will be able to give you custom CSS to hide it manually
