We experience random crashes of editor with given message:

Hey ,

Are you working within 4.8.1? If so, how did you obtain the engine, was it through source or binary? Have you tried deleting your Config, Intermediate and Saved folders from your project folder? If not, could you please try to do that at this time and see if you still run into the same error. If you run into the same error, or if deleting these folders for some reason causes your project not to open, feel free to place them back into your project folder.

Another piece of information that is vital is a solid reproduction of this crash. Are you able to get this crash to happen on a fresh blank project? If so, could you please upload those as a .txt file to your next reply? If you’re not able to, is it isolated to the project you’re currently working within?

Please let me know how this affects your project and the error, looking forward to hearing back from you! Thanks!

It turns out, that it WAS because of “IMPLEMENT_VERTEX_FACTORY_TYPE”, but it only crashes on some machines. We are investigating it right now.

Its 4.8.1 from the launcher. We tried deleting those directories and it didnt help.

Once you’ve investigated the issue on multiple machines, feel free to supply the full error and we’ll be more than happy to look into the issue further for you.

Thank you!
