Thanks for the report, we're aware of this issue and we'll issue a new version very soon.

@JuanFcoMiranda We've fixed the issue on our side, the release would be available in a few days or so. But note that this issue shouldn't block you from using Rider or Uno plugin for Rider, it doesen't affect the execution in any way

[JuanFcoMiranda]

@Takoooooo Yes, I know, but it's pretty annoying to see the error on the bottom bar of Rider.

The release will be available soon.
