Bug – Error detecting Visual Studio installations: System.ArgumentException

Unity version : 2023.1.x
Visual Studio version : 2022
Visual Studio Editor version :2.0.20

When opening the project, the following error occurs: “Error detecting Visual Studio installations: System.ArgumentException: JSON parse error: Missing a comma or ‘}’ after an object member.”

Even after updating Visual Studio Editor to version 2.0.20, the issue still persists, and no similar problems can be found.

Additionally, Unity 2022.x cannot be opened properly, and there is no response when attempting to create a new project. Even when directly launching Unity, there is no response, and no error logs can be found to identify a similar issue.

Note: These are all new projects.
