My Project crashes 1 second after opening

Sorry for the repost .
I uploaded my crash log as well.

I am having problems with my project.
It crashes everytime I try to open it , and this is the message I get:

Assertion failed: Usage->ChannelUsage[Allocation.WeightmapTextureChannel] == nullptr || Usage->ChannelUsage[Allocation.WeightmapTextureChannel] == Component [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Landscape/Private/LandscapeEditLayers.cpp] [Line: 1924]

Can someone please help me with fixing this error?

You can change the map that the editor loads on startup in YourProjectFolder/Config/DefaultEngine.ini → “EditorStartupMap=”

At very least this could help you get the project open.

Also, if you open your .uproject with a text editor you can manually disable plugins. (If a plugin is causing a crash on launch)

Thanks for the suggestion.
I went into my shared assets and deleted the height maps. It solved the issue. I recovered my work because I have the habit of exporting the heightmap file after I paint my landscape.
