I open Unreal Engine and open a project.
Then I create a new map.
Then I click “Save” or “Save As”.
Then it crashes directly:
Script Stack (0 frames) :
Fatal error: [File:./Runtime/CoreUObject/Private/Misc/PackageName.cpp] [Line: 967]
LongPackageNameToFilename failed to convert '/home/username/A/simulation/unreal/Projects/myproject/Content/NewMap'. Path does not map to any roots.
Signal 11 caught.
The problem is, ‘/home/username/A’ does not exist.
The correct path is:
‘/home/username/B/simulation/unreal/Projects/myproject/Content/NewMap’
Note1: I do NOT choose any filepath. I think this is some kind of configuration issue, e.g. ProjectHome.
Note2: I activated also the long filepath option under experimental (But this is not the issue, because it crashes due to the wrong NOT EXISTING filepath).
I deleted all intermediate and binaries folders already and rebuilt the project.
