What is the Lazarus and Freepascal version?

Does the bug occurs also in Delphi?

No

With LCLCocoa the component fails to initialize. The problem seems to reside in the ClipboardRegister of custom formats inside InitializeGlobalStructures. More details and full discussion on Lazarus form: https://forum.lazarus.freepascal.org/index.php/topic,45432.0.html
