Hey @guiltyfeet

This is a known issue on laptops with integrated + dedicated graphics.

Can you check your graphic driver version and either downgrade or update it to one of the versions reported as solving the issue in the following thread: https://forum-new.derivative.ca/t/crash-when-i-make-a-reference/273409/46?u=jetxs

Please let us know if that helps,

Reverting the nvidia driver to 512.95 seems to have solved the issue. Thanks a lot for pointing me in the right direction. Should we expect this issue to be fixed in future builds?

Yes, we have reported the issue to Nvidia, it seems to be a regression bug in the drivers. We’ll update you when we hear of new drivers that address it.
