GPT 4o Team version not reading even one line ascii text files

Has anyone else experienced this and found a solution other than all the boilerplate solutions, (trying different browsers, clearing the cache, disabling the VPN and firewall, running in Incognito, changing DNS servers, rebooting the Computer, etc.?). I’ve already reached out to support over 14 hours ago but am awaiting a response and given it’s the weekend I thought someone may have seen this before and know something I don’t.

At first I was getting “Unknown Error Occurred” in a big red message box at the top. Then, after I reported the issue, the files appear to upload but then GPT 4o can not even tell me what a text file with a single sentence says.

I’ve looked through other recent posts but see nothing this extreme.

I also encounter the same situation. Until I sent this comment, my gpt 4, gpt 4o, gpt with canvas, o1-mini and o1-preview are all unable to parse the uploaded pdf, txt, etc. Actually it acts like I haven’t uploaded the file. However, the customized GPTs can still parse uploaded files and run python code online(except those created by GPT team).
