If you do not have the debugging symbols, you’ll need to go into your Launcher, go to the Library tab, and click the dropdown arrow next to the Launch button of your engine version. In this menu, select Options and ensure you have the Editor Symbols for Debugging option selected (this is a large installation).
Or if you do not have the space for these symbols, you can send the crash report and provide your Machine ID from the CR window, and I can look it up in our database.
