solidworks 2019 crashes on startup

Solidworks crashed during a simulation. When i restarted it, it started loading addins etc, then it stopped and said "A problem caused the program to stop working."

I have uninstalled and reinstalled. I have gone through the repair process for all SW products. There is nothing else I can do and I am seeking assistance.

What can I do? I am in the middle of using it for work.

Is there a technical service that I can contact? The company in Australia who is my provider is out of hours at the moment.

I need to resolve this issue ASAP.
