UE5 - Packaged Textures become red

I have a problem with packaging a project. When I opened the exe file from my pc it looks fine but when I open it on another computer everythings become red. Any idea what is happening here? I saw on another discussion that this problem happened with M1 Macbook, but both computer of mine are on Windows 10 and the package was built for windows platform.

After testing here and there, I think the main problem is your RAM capacity. When your PC is out of RAM, it will make this issue.
