Update your .NET framework
https://dotnet.microsoft.com/download/dotnet-framework

[Sharkpepper12138]

I DOWNLOAD .NET framework4.8,but it still doesn't work.

Did you run the updater/installer then? Doesn't seem like you have, as this error means a certain feature in .NET framework is missing, which only happens with very outdated versions of .NET framework. Minimum required version is 4.5. Newer versions are backwards-compatible.
You can check your version in the Apps & features section in the Apps Settings and look for Microsoft .NET Framework 4.X ...
