Crash when opening project

Hello, I reinstalled my windows, freshly installed UE5 and every time I try to create new project or open existing one, UE crashes and gives me this error. Anyone knows what to do?

if you are using the source version you need to re-build it, if non-source version , you need to reinstall it.

hope it helps,

Thank you for reply! :slight_smile: could you clarify what do you mean by source version? Because I just did fresh install today through epic, same as I did before reinstalling windows… but I have never encountered this error.

So I tried to reinstall both epic and unreal but the problem remained the same.

do you need the open cv plugin?
its crashing
if you install 4.27 and make a simple 3rd person does it build
are you able to open 5 and build a basic blueprint 3rd person?
basic, no plugs
if you can’t even build a basic blueprint 3rd then
you might have to use 4.27
gfx card/machine specs?

I am beginner so I have no idea if I need the plugin to be honest. But I used 5 with no problem before reinstalling windows. I have 3070, 64 gig ram, amd 5600. And no, I cant open 5, I just get to the window where I can choose which project I want to open and when I try to open it, UE crashes and gives me this error.

PROBLEM SOLVED!!! I went through the crash file carefully again and I noticed “Failed to load required Windows Media Foundation libraries”. So I installed Media feature pack and now everything works. It was because I have N version of W10… and I had no idea that this could be a problem.


that would hoop a lot of things
glad you found it.
