The error message “Assertion failed: SingleJob.Output.ShaderCode.GetShaderCodeSize() > 0” is indicating that the output of a shader compilation job is 0 bytes in size, which is unexpected. This is likely caused by a problem with the shader code or the shader compiler itself.

Here are a few things you can try to troubleshoot the issue:

  • Check the shader code for any errors or syntax issues. Make sure that all variables and functions are properly defined and that there are no missing semicolons or other syntax errors.
  • Try disabling any custom shaders or material nodes that you may have added to the project, and see if the error still occurs.
  • Check the shader compiler log files to see if there are any error messages related to the problem.
  • Make sure that your GPU and GPU drivers are up to date.
