I do not know what could have caused my map to crash, perhaps after updating the UnrealLink proposed by RiderUE and after that, I cannot log into my map, despite the fact that I am told “Failed to find the world in already loaded world package”. And so every time I go to the UE project. Despite the fact that my map is where it always was, there were no problems, I did not touch anything. It was only after the UnrealLink update that I got this surprise. Ue4 does not see my map in the editor, but it is in the Content root folder. Someone had the same problem, but they ignored it, I hope they won’t ignore it now.
