Hi @RenataKay7 We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.😊
This is not a problem and you do not have to perform any troubleshooting checks.
Look at the level goal, there are 20 light chocolates left to break, but you have no light chocolate left on the board.
Until the chocolate meets its goal, you need to have at least 1 light chocolates left so that new light chocolate can be born from it. Your level failed because there is no light chocolate left on your game board.😜
