I installed version 0.37.0 over 0.36.1, made uno clean on project and fuse preview crashed with errors:

I removed version 0.37.0 with script [https://gist.github.com/Tapped/daa78c08882f33b0c7c3](https://gist.github.com/Tapped/daa78c08882f33b0c7c3) and install it once more, but nothing changed. Next I removed 0.37.0 and reinstalled 0.36.1. Everything works, but during build phase I got error:

```auto
ERROR: Could not connect to the feed specified at 'https://api.fusetools.com/packages/v1/nuget/v2'. Please verify that the package source (located in the Package Manager Settings) is valid and ensure your network connectivity.
(unknown): E0100: Package Fuse.Scripting.Jurassic:0.47.7 was not found
?: Error E0100: Package Fuse.Scripting.Jurassic:0.47.7 was not found

```

Despite this error, my app is running properly. This error didn’t appear during first installation of 0.36.1 three weeks ago.
