I'm having the same problem. I've tried some of the techniques above but nothing is working. Its so frustrating, I was using the space bar for the Hand Pan tool all the time before, but now I can't. I've recently got a new MacBook Pro and I'm working on shared files. I'm on the latest Mac OS system (Version 10.15.7) I'm not sure if the combination of these two is having an affect using the spacebar for Hand Pan tool. It flickers on briefly but goes away. It's driving me crazy!!
