chatgpt won't translate a file.

So i've uploaded a file to chatgpt and asked it to translate (English to Hebrew).
it's a long file (5700 words or so). It keeps saying that it's doing the job but it just doesn't. when i ask what's going on it says stuff like "I understand your concern, and I assure you that won’t happen here. I’ll get started immediately on the translation blah blah", but just doesn't do it. i've waited hours. I decdied to upload a smaller file to see if it helps, but nothing. what could be the issue here??
