O1, canvas, file vision, web search, code inter... - Not Works!

At some point, everything mentioned above just stopped working. No matter which model I use, it just works as the regular 4o. The search doesn’t work, and o1 doesn’t activate reasoning/chain of thoughts. I’ve tried all browsers, in clean browsers, on different PCs, with different IPs, and through VPN – nothing helps. Of course, my account is ChatGPT Plus and it’s paid.
I really don’t know what to do anymore. Support, as usual, isn’t responding.
