Yeah I am having the same issue with crashing maps. I’ve tried to track it down but there seems to be multiple things causing this corruption of a saved map file.
I have found that if I even edit (not even placed in the level) certain blueprint actors and then save the level it is corrupt next time I try to load it.
I have also had a material with a material function corrupt the saved level.
I have submitted the dump every time it has happened so hopefully they will have a chance to go over it.
Also I can’t even create a new blank blueprint project, I just get the error.
Missing MyProject422 Modules
The following modules are missing or built with a different version:
DatasmithCADImporter
DatasmithDataPrepEditor
DatasmithDataPrepLibraries
DatasmithVREDImporter
DatasmithDeltaGenImporter
DatasmithGLTFImporter
DatasmithFBXImporter
DatasmithImporter
StaticMeshEditorExtension
MeshProvessingLibrary
VariantManager
Would you like to rebuild them now?
And if I answer YES it fails to compile and says I should compile from source, if I answer NO it just goes away.
The only way I could fix it was to edit the .uproject file and change “Enterprise” to false (or remove it)
I wish if you created a new Blueprint Project (Not an Unreal Studio Project) it wouldn’t stuff Datasmith in there anyway.
