MSBuild Error when I create a UWP solution in rider

My environment:

VS not installed. Only Rider.

Lasted .net Core 3.1 installed

Lasted Windows 10 SDK installed 

-----------------

When I new a UWP solution in the Rider and use the default template. Rider can not find the MSBuild

In the `File | Settings | Build, Execution, Deployment | Toolset and Build' Setting.

The Path of the MSBuild is point to the Jetbrain's MSBuild in the Rider folder.

The log is.

```

I am sorry I can not change the language of the log to the English.
