Space bar and shift key not working - can't complete tutorial!

Platform: Windows 10 21H2 x64.
Version: latest as of today
Keyboard layout: English (United Kingdom)
Problem: shift key and/or space bar does not work at all, therefore I am unable to complete the intro tutorials and can’t even begin to use the program.

I am so disappointed and frustrated after my troubles even getting this program installed. I am really at a loss with how frustrating it has been to even begin using this software.

I’m happy to provide whatever technical information you need but please don’t ask for a screengrab or video of the problem because it’s exactly as I described: Shapr3D is the active, focused window. I’m able to rotate the camera, interact with surfaces, type in numeric dimensions etc. but space bar does not focus on a face, and shift does not allow multi-select. I’m therefore stuck on tutorial 7.
