Why might my photo be considered a copyright infringement?

Hello,

I recently submitted a photo of a lake shore that contains no identifiable objects, buildings, or other copyrighted elements. However, the photo was rejected due to a copyright infringement issue.

I carefully reviewed the content and ensured that it was entirely original, taken by me, and does not include any trademarks, recognizable private property, or other restricted elements. Could someone clarify why this might have been rejected and how I can address this issue?

I would appreciate any guidance or explanation.

Thank you in advance!
