MACOS 10.14.6 Illustrator 2021 cloud.
Everything worked fine yesterday. New 2021 will not allow me to work on ANY project, old or new because the toolbox is locked. I launched Illustrator, opened a file, wanted to edit some text, selected the Type Tool, moved the cursor to the desired type and the cursor didn't change to the TYPE tool but showed a paintbrush with a locked icon attached. No matter which tool, or file (I tried several, also a NEW) the result was the same paintbrush icon.
