I'm having the same problem. Worked fine 13 May 2020 but following automatic update, crashes when using any update income or deduction button. It's possible to make changes in the forms directly without a crash. I have Premiere and it's running on Windows 7. Tried uninstalling and reinstalling. Same issues. Obviously something to do with the update (not sure why tax forms seem to need updating just about every time you restart, even though the tax filing deadlines have passed - what does that say about the accuracy of your filing if you finished yesterday?).
