High CPU usage

When the plugin is enabled I have a consistent 40%-50% CPU load on the Rider process on Windows 11.
When I disable the plugin it goes back to normal (<5%>.

I am running nightly builds of Avalonia and AvaloniaRider 1.0.3.104 on Windows 11.

All I see in the logs is the following exception, but I don't know if this is related to the issue, or normal when the Plugin should refresh the preview.

```
