### Godot version

4.0 beta 10, mono edition

### System information

Windows 11

### Issue description

No matter what I do Project Camera Override can never detect a game instance.

Of relevance: I can see remote nodes. I can see the output in the console. I can see the output in my IDE of choice (Rider). I can toggle debug mode.

It's just the camera that is unable to detect the game instance.

### Steps to reproduce

This happens everywhere, including on a brand new projects where the only nodes are a 2d camera and the Godot svg icon for testing. This also seems to happen when not using Rider as a third party editor.
