I just wanted to chime in to say I'm having a similar issue with Adobe XD. I have a brand new MacBook pro laptop with Magic keyboard. I've been using the magic keyboard for work and the shift key has been sticking like crazy. I thought, man, I got a faulty keyboard. I even tried cleaning it, but no luck. Well, I just started working directly off of my laptop without the external keyboard, and it's still sticking! That's how I ended up here. It must be a software issue. A user above mentioned a potential issue with a wacom tablet which I am using. I'll try experimenting with that and see what happens.
