Refactor: Remove redundant checkAlError call for performance

removes the repeated call to the `checkAlError` method. The repeated string creation and the associated overhead of the error checking can negatively impact performance, especially in a frequently executed game loop. By removing this redundant check, we aim to improve overall performance and reduce garbage collection pressure.
