Hello there! Reached out to see if we can help. This looks like a typical crash log. Are you able to clean the log, attempt the crash again, and then provide the new log? If you’re able to share that with us it’ll probably help us identify it easily!

Hello, I have the same crash as the user specified.
Could you help troubleshoot it with me?

Upon starting UEFN, it loads to 100%, then when the project selection screen appears, UEFN crashes with the error.
