[emmergency] Sudden change in ChatGPT 4 tokens (character) limit!?

Hey guys, I’m so shocked that ChatGPT 4 changed in about 7 days! last week I sent a request with about 100/000 characters in length. That was ok and my activity was done correctly. Yesterday I tried to submit a request with fewer characters about 80/000 characters in length, but ChatGPT 4 refused my order and showed me this message:
(The message you submitted was too long, please reload the conversation and submit something shorter.)
I need emergency help because, with this amount limit, I can’t use ChatGPT 4 anymore! No one in online chat tries to help me and they refuse to answer one of their old customers!
I tried many different scenarios, like reloading, changing IP, changing the device, changing location, changing codes, splitting the codes, etc.
Thanks for helping me.
