Hi, I came across your post. I tried to install UE5 as well (and UE4 before that) on Ubuntu 20.04, following exactly the same link you mentioned. There’s no error or anything, building & compiling were succeed, but it took me almost an half hour everytime to open UE. My machine is Core i7 with 20 ram, so I doubt there’s should be an issue with it, even Unity runs smoothly in my machine. I read that many people have the same issue and I read there’s a workaround to open a project instead of opening UE directly, it works but simply not practical for me.
Do you have the same issue , any advice ? And how do you open UE, from terminal, like the tutorial, or launcher ?
