  Outputs:
    - ExtraContent: built content files
      - ContentDir: the relative path of the embedded folder to contain the content files
-->
<Target Name="RunContentBuilder" DependsOnTargets="PrepareContentBuilder">

  <!-- Execute MGCB from the project directory so we use the correct manifest. -->
  <Exec
    Condition="'%(ContentReference.FullPath)' != ''"
    Command="$(DotnetCommand) $(MGCBPath) $(MonoGameMGCBAdditionalArguments) /@:&quot;%(ContentReference.FullPath)&quot; /platform:$(MonoGamePlatform) /outputDir:&quot;%(ContentReference.ContentOutputDir)&quot; /intermediateDir:&quot;%(ContentReference.ContentIntermediateOutputDir)&quot; /workingDir:&quot;%(ContentReference.FullDir)&quot;"
    WorkingDirectory="$(MSBuildProjectDirectory)" />

  <ItemGroup>
    <ExtraContent
      Condition="'%(ContentReference.ContentOutputDir)' != ''"
      Include="%(ContentReference.ContentOutputDir)\**\*.*">
      <ContentDir>%(ContentReference.ContentDir)</ContentDir>
    </ExtraContent>
  </ItemGroup>

The $(MGCBPath) property is the only parameter which is not quoted in the command. You can also see that in your error message.

So quoting this property will likely fixing this bug.
