[SOLVED] Exception has been thrown by the target of an invocation on a pipeline

Exception has been thrown by the target of an invocation on a pipeline

I've created a build pipeline for a .NET Framework project. When the pipeline is triggered by a pull request, I've got this errors on the task: 'NuGet restore'

##[error]The nuget command failed with exit code(1) and error(Error parsing solution file at d:\a\1\s\***.sln: Exception has been thrown by the target of an invocation. The project file could not be loaded. Could not load file or assembly Microsoft.Build.Framework, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a or one of its dependencies. The system cannot find the file specified. d:\a\1\s\***.sln)

##[error]Packages failed to restore

When I try to compile the solution on my local computer after merging with the target branch, I don't have any conflicts or errors.

Here is my YML file:

pool:
  name: Hosted Windows 2019 with VS2019
  demands:
  - msbuild
  - visualstudio
  - vstest

steps:
- task: NuGetToolInstaller@0
  displayName: 'Use NuGet 4.4.1'
  inputs:
    versionSpec: 4.4.1

- task: NuGetCommand@2 # --> This task fails.
  displayName: 'NuGet restore'
  inputs:
    restoreSolution: '***.sln'

- task: VSBuild@1
  displayName: 'Build solution'
  inputs:
    solution: '***.sln'
    platform: 'any cpu'
    configuration: 'release'

- task: PublishSymbols@2
  displayName: 'Publish symbols path'
  inputs:
    SearchPattern: '**\bin\**\*.pdb'
    PublishSymbols: false
  continueOnError: true

- task: PublishBuildArtifacts@1
  displayName: 'Publish Artifact drop'
  inputs:
    PathtoPublish: ***
    ArtifactName: 'drop wa'

What's wrong with it?
