Editor 4.9.2 crash immediately

HI,

editor 4.9.1 and 4.9.2 crash when it open or as soon as I click something. Worked fine before.
I updated my latest Nvidia drivers. I need to have it work because I use it with my students.
Can you help identify the problem?
many thanks

Thomas

Hi tharmine,

We’ve got a bug in our system for this (UE-22072), but we currently don’t have a way of reproducing it.

Is this occurring on all projects? If it is only in one project, could you upload the project to cloud storage and PM me the link on the forums? In your forum message, please include a link to this thread.
