HDRP Render Pipeline Issues

Modified

I find lines in the settings files like this:
```
  m_CustomRenderPipeline: {fileID: 11400000, guid: b9f3086da92434da0bc1518f19f0ce86,
    type: 2}
```

If I keep these lines, the editor's background is very dark.
But it becomes normal after I delete these CustomRenderPipelines.
