I have the exact same issue using TT Home & Business on Windows 7 Pro. Can not update w/o programming crashing. Help desk had me try running program in Windows 7 compatibility mode - made one update and then the program crashed and would not even restart. Had to turn off compatibility mode to restart and ended up with same problem. Of course the help desk blames the problem on running "unsupported" Windows 7, but it is not like at this late stage of 2019 updates the programmers needed to access some new feature in Windows 10 not supported in Windows 7. Just a poor rollout of an update that was not properly vetted before being released.
