Why can't I log in to ChatGPT?

Hello, OPENAI. I am a Plus user, I logged into my account just now, and it was prompted “Oops!
You do not have an account because it has been deleted or deactivated. If you believe this was an error, please contact us through our help center at help.openai.com 19.”
I didn’t find any helpful information in the help center, then I came here. I do not believe I have violated any policies and regulations or any of the relevant usage rules. Chatgpt helps me a lot with my development and research. ChatGPT expressed the willingness of embracing the AIGC, but account had been deleted or deactivated. I don’t understand. Please help me recover my account.
Or do I use any sensitive words I have talked with ChatGPT4 before without awareness. Please at least let me know why my account was disabled. Please assistant me to recover my account back. I will strictly abide by the rules.
Sincere gratitude.
Wish you all have a nice day!

Kind regards,
