Hello I have setup a new project in SonarCloud, the first run is successful, every run that follows fails. I have removed the project and re-added but it continues to happen. I have also checked the Background Tasks, and only success are there.
ALM used (GitHub, Bitbucket Cloud, Azure DevOps)

The issue seems to be that you have set js as a filename extension for Apex language. However, this extension is already used for JavaScript files, which makes the configuration invalid.
Please adjust your configuration to remove js as a filename extension for Apex, and try to analyze again. Let me know if this solves your issue or not.
