Cannot resolve symbol 'System' or any other symbols in Unity project
I wasn't getting any syntax highlighting, then I saw the OFF in the top right corner. It says that analysis is not supported for this file. Then when I chose Highlight: All Problems, I get red errors for every symbol in the entire CS file. The event log is also not giving me any clues.

Hi @...!
What Rider version do you use? Could you please collect logs? Please follow these steps:
- Navigate to `Help | Diagnostic tools | Choose Trace Scenarios` and enable Trace scenario for Project model;
- Reopen your solution and one of the corrupted files
- create a new bug report via `Help | Report a bug` with attached logs;
- Disable Trace scenarios;
Also please attach screenshots of your Solution Explorer and File | Settings | Editor | Inspection Settings => Elements to skip. Thank you!
