Had same problem. Saw a bunch of people say quitting safari worked.. I wasn't using safari but Chrome. Closed Chrome and my spacebar quick key worked again.
I must say since updating to Mojave, I have had NOTHING BUT PROBLEMS with my Adobe programs. Yall need to GET WITH THE PROGRAM AND FIX ALL THE BUGS. This is getting ridiculous that I have to troubleshoot DAILY due to Adobe/Mojave not meshing
