I’ve tried opening it in both 4.25 and 4.26. It always crashes the engine within 2 minutes. After the Unreal crash reporter appears, the entire system freezes and goes unresponsive until restarted. I checked the Task manager, everything remained normal upto the freeze. Note that my PC is completely fine - any other UE4.26, 4.25 and 5 projects run without any problems. My PC specs are: Ryzen 3600, RTX 2070, 32Gb RAM.
