Root Cause

C# script has a syntax or type error preventing compilation. Unity cannot enter Play mode until all compiler errors are fixed.

Workarounds

  1. 95% success Read the exact error code and line number in the Console
    Double-click the error in Console to jump to the exact line in your IDE

    Sources: https://docs.unity3d.com/Manual/upm-ui.html

  2. 85% success Check for IDE/Unity version mismatch with .NET API compatibility
    Edit > Project Settings > Player > Api Compatibility Level: .NET Standard 2.1 or .NET Framework
  3. 82% success Ensure all referenced packages are installed and up to date
    Window > Package Manager > check for errors or missing packages referenced in your scripts

Dead Ends

Common approaches that don't work:

  1. Delete Library folder to force recompilation 85% fail

    Library folder is just a cache. If the script has a syntax error, recompiling produces the same error.

  2. Reimport All assets to fix script errors 80% fail

    Reimport is for asset pipeline issues, not C# syntax errors. Does not recompile scripts.
