More info: it’s just the one project that does this. My other projects open just fine. This project in particular is a labor of love that I’ve been working on for months and I’ll be wrecked if I have to start over AGAIN. If someone could please just maybe point me in the right direction to figure this out on my own? I love Unreal Engine, but it feels like the slightest misstep can lead to devastating consequences…

Update! I found a thread (How to I stop my UE5 project from crashing on startup?) that recommended deleting the saved and intermediate folders in my project and it opened!
