Twinmotion wont open

Hi, I was having an issue where shadows were not displaying correctly, I found a solution on another forum discussion that suggested I upgrade the Quality settings, which I did from Low to Med over all catagories. This seemed to work and i was prompted to restart Twinmotion, but when I did the program crashed on startup. It now crashes on startup every single time i try to open it.

is there a way to change the Quality settings back to default without opening Twinmotion? or any other work around?

I have tried uninstalling and reinstalling but it still crashes on startup.

Thanks!
