Hi and Welcome to the King Community

Thank you for reporting , Ill pass this feedback to the game team , In the meantime

Please Check app update - Log out game - Restart Device - Open game and Log in.

If you still aren't able to make any new purchase in the game, please contact Player Support from the game's Settings and Help Center so they can take a closer look at it. Remember to choose "Purchases & Gold Bars" as the subtopic!
