Refactor resolveBlocked method in RenderService class

The resolveBlocked method in RenderService class has been refactored. We removed the process method and added the remove method from worker object, making the code easier to reason about. This also fixes the issue where playerSink object might not have been correctly updated before performing the remove operation.
