Build Failed, Launch failed, unknown error

Hi, thanks for your engine.

Today we was tryed to build huge map project and launch him outside of editor and received error on launch.
Log File here: Build_Failed_DebugLog.txt — Yandex.Disk

Please, tell me about our error, and why i can’t launch the map.

Thanks very much!

Heya brother,look i had the same problem and it was because of the “substance” plug in…dont know if u have this plugin installed but maybe its some other stuff you downloaded or added to your map. hope it works for you!
