Hey there.
To start, sonar.opencover.reportPaths doesn’t’ exist, while sonar.cs.opencover.reportsPaths does.
If you plan to use sonar.cs.opencover.reportsPaths to import code cover, you probably want to change /p:CoverletOutputFormat in your dotnet test command to /p:CoverletOutputFormat=opencover.
If this isn’t successful, I would suggest looking in the logs of the SonarQubeAnalyze step, which should provide information about whether or not the report was found / what happened when the report attempts to be processed.
