The web version of ChatGPT always ends up freezing

Hi everyone, I'm having an issue with the web version of ChatGPT. Please note: this issue occurs on all my browsers, it's the only site that has this problem, and apart from that, my computer works perfectly. When I log into the web version of ChatGPT, everything works perfectly for a few minutes. I can navigate between conversations, write and send text. No problem. But after 5-20 minutes, everything crashes, as if the site has frozen completely. It sometimes takes 30 seconds for the text I've entered to appear on the screen, and it's impossible to switch conversations without waiting.
