Developer Notes

To work around this issue

  1. Close your 4.19 Editor
  2. Open Engine/Config/ConsoleVariables.ini
  3. Comment out r.XGEShaderCompile = 1
  4. Save the file
  5. Launch your 4.19 Editor

The editor stalls out at 45% while opening to the project browser. This is occurring on machines with Windows 7 and 10. I tried using VS attach to process but it didn't provide very much. Opening the editor from a console resulted in "'XGEControlWorker.exe' is not recognized as an internal or external command, operable program or batch file. Disabling r.XGEShaderCompile = 1 in the ConsoleVariables.ini has loaded the engine.

Steps to Reproduce


Open the Gamedev launcher


  1. Update Release-4.19 to latest
  2. Open Release-4.19
