Once upgrade to Max, all requests returned internal_server_error

Bug Description
I have upgraded to Max plan, but once I finished placing the order all Claude APIs are now returning internal_server_error. I tried logging out and in again on Claude Code, it doesn't work. Then I tried Claude web, Claude desktop and Claude app. All requests returned internal_server_error. I am no longer able to use my Claude account at all.
