Unreal keeps crashing at 94%

Hi,

When I try to open UE4 14.3 with a project, it keeps crashing at 94% for some bizarre reason. The weird thing is that this project runs fine with my lower spec laptop while I’m working on a very good PC that is capable of running Unreal fine.

Here is the log file I get:

What should I do to resolve this?

Mr_Doctor_Professor_Jackoasta,

I cannot speak to why your project will not open on a higher end machine in UE4.14.3, however, when this occurs you can open the DefaultEngine.ini and change open the default map to open to “none.” It may be that the file directories are slightly different between the two machines -this would make sense if you started on the lower end laptop and moved the project to the higher end system.

If the above does not work, try deleting the DerivedDataCache folder from the UE4.14.3 install directory of the higher end machine, then try opening the project. If it still doesn’t work, delete the Saved and Intermediate folders and try opening again.

Let me know if this does not resolve the issue.

Deleting the EditorStartupMap setting in the DefaultEngine.ini worked for me in 4.18.3! Thank you.

However, attempting to open the map that was set as the EditorStartupMap still leads to the crash.
