Does anyone know how to withdraw the coins of 1.4.21.1

Does anyone know how to withdraw the coins of 1.4.21.1? I just refilled my lost height and found that when I decrease INC, it prompts rpc erro wait or something like that. How can I help? Has the method of withdrawing coins changed? Do I need to run the latest node and run to the highest frame rate to withdraw coins? I can’t find coins
I submitted proof of 2.0 before the window closed
help thanks
