Hello, one day my project stopped saving. The following error appears: The asset ‘/Game/Maps/Level1’ (Level1.umap) failed to save.
Cancel: Stop saving all assets and return to the editor.
Retry: Attempt to save the asset again.
Continue: Skip saving this asset only.
Before this everything was fine and worked as it should. But now nothing is saved and I can’t continue to work(. I’ve been having this problem for about a week now, so it’s definitely not a matter of 2 UE processes. I’ve looked all over the Internet and haven’t found the answer. Please help me with this problem.
Check if you have another instance of the editor open. Unreal fails to save assets / levels if there are two open at the same time. It might be an old open process on your pc called UnrealEditor. You should only have 1 instance of it running.
It will only save once 1 is left open (try finding out which one is the current one and which is the old one before termination)
did the file somehow become write-protected/Read-Only ?
if you create a new blank Level does the Editor allow you to save that ?
was the project added to, or had its source-control/revision-control status changed? are you signed into the source control if it is attached?
is that the entire error message? are there C++ classes/objects that might have been declared as DefaultToInstance though this will often have additional information as a warning about ‘Archetype object’ which can prevent saving.
When opening a new scene in the same project, the error does not disappear. However, when creating a new project, everything works as it should. I haven’t added any C++ code to the project yet. I didn’t go into the version control system, but even without it everything worked as it should. Also included is the full error screen:
I found the file that causes the error, but at first glance everything is fine with it.
Adding: at other levels of the same project, an error appears with changing the names of the levels:
The asset ‘/Game/Maps/Level2’ (Level2.umap) failed to save.
Cancel: Stop saving all assets and return to the editor.
Retry: Attempt to save the asset again.
Continue: Skip saving this asset only.
However, there are no “umap” data files in the root folder of the project. I am confused, I ask for your help in solving it.
Hello everyone again, after understanding the intricacies of that error, I saw a warning on the command line: Insufficient writing permission to save /Game/Maps/Level2. Having decided, out of curiosity, to run UE5 as an administrator (it is important that you need to launch the editor and not the Epic Games launcher), everything worked for me! Many thanks to those who helped solve my problem, my respect to you.
