Hello,

This crash is related to attempting to open 4.11.1 while having the substance plugin enabled. What you’ll need to do in the meantime until they release a fix for the plugin is go into your engine installation directory and go to Engine->Plugins->Marketplace and delete the substance folder. After you do this, you should be able to launch your engine.

Keep an eye out for a fix to the substance plugin in the near future, which should allow you to work with it in 4.11 again.

Have a great day
