Thanks for the help!
I did find a similar post here: ue5 crashing, anyone can help me?
That looks like the same error, but resetting all Nvidia control settings to default did not fix it.
I am on a laptop with Nvidia GPU with 2 external monitors.
I was able to narrow down exactly to where my crash was happening I believe. It seems it 100% crashes whenever I close the “New/Open project” dialog. Because I didn’t have “open last project on startup” selected, immediately after choosing my project to open it would crash because that dialog would close. I have a work around at least now to enable “open last project on startup” so that dialog doesn’t open.
It does also seem related to external monitors like you mention, when UEFN opens, I often drag it from the laptop primary display onto one of the external monitors.
My integrated and Nvidia GPU drivers are up to date.
I’ll try to force UEFN to use Nvidia through the control panel now.
