I have another dotnet project where code coverage is reflecting for which we have used the same sonar configuration and dotnet test task arguments. So, I have compared between logs between these projects and found the following difference
logs of Dotnet project for which code coverage is calculating

For these two projects, able to generate .trx file and …coverage file
Is there any difference in the configuration of your SonarCloudPrepare tasks, specifically where you may explicitly be pointing to a coverage report in one but not the other? You should make sure you check the Advanced > Additional properties section of this task.
Then I think you’ll have to check if the file (coverage.opencover.xml) really exists for your second project. Probably, there’s some difference in the configuration of how the code coverage repot is generated.
Long story short – make sure for the second project that coverage.opencover.xml really exists where you expect it to.
