Hello ViTaLC0D3R,

I have a couple questions about your project to help investigate your issue further.

  1. Have you deleted your saved and intermediate folders?
  2. Are you using any third party plugins?

Thanks!

I have tried deleting my saved and intermediate folders. I think I have engine plugins installed but I don’t have any project plugins.

I have a couple more questions about your issue.

  1. Did you package your project again and try reopening after deleting those folders?
  2. Looking through your cook log for your project you have an object “Widget3DPassThrough” in your project before you Critical error, are there any warnings or errors for the object in your project?

Thanks!

I’m going to try starting a new project.

Reinstall Direct X.

The Editor requires PCD3D_SM5, shader model 5. Its not finding it because DX12 is not properly installed.

Reinstalling DX12 will fix this issue.
