A colleague had previously installed Cocos Creator, but later received this error while opening a project:
In this case, uninstalling and reinstalling the exact Cocos Creator version required by the project resolved the problem.
Before reinstalling, record the project version and back up any editor settings. If the error remains, inspect the editor logs, confirm that the project path is accessible, and try opening a new empty project to distinguish an installation issue from a project-specific one.
