"Failed to load map! Umap appears to be an asset file" [UE 5.1.1]

Hello !

I currently have the “Failed to load map” error message when opening UE5:

My map “SWU_Onboarding” just disappeared from the UE5 Content Browser but still remains in my Windows Content Project file.

I saw on another forum that in “Maps and Modes” the problem can be solved by selecting a “Default map” in the “Editor Starter Map” then close and starting UE again and selecting the “faulty map”. But on my side I do not see my “SWU_Onbaording” map.

I tried to create a new project and copy paste the .umap on the new project folder, my clean maps appears but the “SWU_Onboarding” doesn’t.
I uninstalled Unreal Engine 5.1 and re installed it, nothing had changed.

I don’t have autosaved enable, I don’t have the project on any Git or Perforce.
Any suggestions please ? Thank you for your help.
