Critical Error thrown while packaging

Hey guys! I just wrapped an update up for my game on Steam, and I have run into a serious issue while packaging that I can’t seem to resolve. Every time I try packaging, everything goes well for the first 3 or so minutes, and then I get this critical error and the build fails:

LogWindows: Windows GetLastError: The operation completed successfully. (0)
LogThreadingWindows:Error: Runnable thread RenderThread 0 crashed.
LogWindows:Error: begin: stack for UAT
LogWindows:Error: === Critical error: ===
LogWindows:Error: Assertion failed: (GIsCriticalError || !NumMarks) [File:D:\Build++UE4+Release-4.16+Compile\Sync\Engine\Source\Runtime\Core\Public\Misc/MemStack.h] [Line: 90]
LogWindows:Error: Crash in runnable thread RenderThread 0
LogWindows:Error: end: stack for UAT
LogExit: Executing StaticShutdownAfterError
LogWindows: FPlatformMisc::RequestExit(1)

This happens ever time no matter what I change. So far, I have tried the following:

  • Refreshing, recompiling, and saving all new blueprints
  • Setting “Build UAT” to ‘true’
  • Packing via the file menu and the project launcher
  • Cooking while excluding certain maps
  • Restarting my PC
  • Restarting the editor
  • Recompiling C++

This may be something very simple or complex, and I am really hoping for some assistance. I have also attached the build log. Please let me know if I need to provide any additional information. Thanks
