When using the type tool and you tap the keyboard to bring up the keyboard it sometime crashes.
Need more information here – does the application crashes while brining up the keyboard or is it that the keyboard collapses as soon as you bring it up?

Your keyboard won't type issue could happen just because your keyboard or the system that your computer is running gets stuck somehow. Once your keyboard is not working, you can firstly restart your computer. A simple restart can always solve computer woes.
Yeah I’m having this same problem. I have close the app completely to bring up the on screen keyboard for typing. The keyboard won’t come up otherwise . Sometimes it works but most of the time it doesn’t.
I have noticed the app crashing when trying to input a decimal point in the properties section.
I have been having lag issues using the keyboard too
It freezes when I bringing up the keyboard.
I tap the type tool, then tap the area you wish to type, then tap the keyboard to start typing and it then freezes. Then switching between the full bottom onscreen keyboard and the mini floating keyboard is a pain. Once to are in the mini keyboard it won't switch back. I am using the 2nd generation iPad Pro 12.9.
