I even tried to downgrade Newtonsoft.Json but that didn't help.

Which command does actually cause the error?

Is it the first line:

dotnet test --collect:"XPlat Code Coverage"

Or the second:

"\users\YOUR_USERNAME.nuget\packages\reportgenerator\5.4.1\tools\net8.0\ReportGenerator.exe" -reports:\TestResults*\coverage.cobertura.xml -targetdir:\coveragereport

If the first line? If yes, then I probably can't help. Maybe you have to update the Microsoft.NET.Test.Sdk dependency?
ReportGenerator does not have a dependency to Newtonsoft.Json.

Hey @danielpalme Thanks for your prompt response. The first line works perfectly fine from Developer PowerShell. It gives output with all the passed tests along with TestResults\<GUID>\coverage.cobertura.xml files.
The problem is when I run with the second line. I even tried to update Microsoft.NET.Test.Sdk to the current latest i.e.17.11.1 but that didn't work.

Here is the test project looks like if this helps...

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <IsPackable>false</IsPackable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="coverlet.msbuild" Version="6.0.0">

I use the same commands in my projects and it works fine for me.

The error message seem strange to me:

An assembly specified in the application dependencies manifest (testhost.deps.json) was not found:
package: 'Newtonsoft.Json', version: '13.0.1'
path: 'lib/netstandard2.0/Newtonsoft.Json.dll'

ReportGenerator does not have a dependency to Newtonsoft.Json.

I have no idea what's wrong with your setup.
If you like, you can create a minimum sample, then I can have a closer look.
