Are there any errors when launching hammer? I know 20H2 is having issues.
No, it simply appears as a process in the Task Manager and then crashes soon after. Hammer is supposed to edit a couple of files every time it's launched/closed, but nothing is being changed. I've also run the compatibility troubleshooter but it still won't let it launch at all.

Apparently it won't launch if the game itself is yet to install DirectX on first-time setup. Now that I have, Hammer finally runs.
