Just upgraded to 2.5 on Mojave, and when working in a score the keyboard freezes every few minutes. I can't esc out of anything, enter notes from the keyboard, playback with spacebar, bascially no keyboard entry is accepted. After a short period of time, a minute or a few, this fixes itself and I can work again.
I reported this before, and it is still a problem. Unfortunately, I can't specifically say anything I do is causing this, but it happens when editing or navigating, not in input mode.
