Workarounds

  1. 95% success Go to Project Settings > Graphics, and under 'Scriptable Render Pipeline Settings', assign the UniversalRenderPipelineAsset (e.g., from Assets/Settings/URP-HighQuality.asset). If missing, create a new one via Assets > Create > Rendering > URP Asset (with Universal Renderer). 
    Go to Project Settings > Graphics, and under 'Scriptable Render Pipeline Settings', assign the UniversalRenderPipelineAsset (e.g., from Assets/Settings/URP-HighQuality.asset). If missing, create a new one via Assets > Create > Rendering > URP Asset (with Universal Renderer).
  2. 90% success If the asset file is deleted, recreate it: Right-click in Project window, select Create > Rendering > URP Asset (with Universal Renderer), name it, then assign in Graphics Settings. 
    If the asset file is deleted, recreate it: Right-click in Project window, select Create > Rendering > URP Asset (with Universal Renderer), name it, then assign in Graphics Settings.

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Reimporting all assets does not assign the missing pipeline asset; the Graphics Settings need manual update.

  2. 50% fail

    Reinstalling URP package without assigning the asset in settings leaves the error unresolved.
