Draftsight won't load

Struggling to run Draftsight on my machine. 2019 version was working and now it's not. Just before it stopped working, my hard drive was placed in another pc as my original one was kaput.  

I've since uninstalled 2019 and re-installed 2021 but still not working. Attached dump file, Draftsight opens but crashes before you see main screen.

Similar problem occurred on 2019 where logo would appear but nothing would happen.

Can you assist?
