Latest WIP crashing right after start

just installed the latest WIP (first time) and when I open it, the splash screen shows, rhino windows opens viewports show up, and then everything just closes.

Installed latest nvidia driver.

I see there is no safe mode shortcut. What can I do to check what is happening?

I am on a Laptop with dual GPU, I tried forcing Rhino WIP to use Nvidia chip, but no change.

this is sysinfo from Rhino 8:

thanks David, this worked.

I disabled maxwell and bella plugins (don’t have them up to date) and now I can start Rhino 9

Good to hear. Frequently third party plugins do not work with WIP versions of Rhino.
