Unreal 5 failed to load map Error

[Jpenalve]

I've been trying to open my environment Ue5 file but keep getting this error. I have tried on 3 different computers using unreal 5.0.3 & 5.1 to try and open with but nothing.

You doing this at the lab or at home? It looks like it thinks you've opened this with a newer version of Unreal somewhere or another. On your home machine, have you double-checked that you don't need to update UE5?
