Problem with submitting low-quality or blurry icons consistently.

Question

I have been using the same icon to submit my game to the store for a while now, but recently it has been rejected for being low quality or blurry. This is surprising to me since I have submitted five versions of the game with the same icon, which was accepted previously. What could be causing this issue, and how can I resolve it? Please provide any information regarding the technologies used and any error codes or stack traces, if available. Additionally, if someone has experienced this issue before, please provide steps that have helped successfully resolve the issue, or any relevant documentation that would be helpful. Code snippets, logs, and additional details are welcome.
