Error updating GPT after document update

I’ve been building a custom GPT for a few months. I got to a point where I went and replaced one of his files with a different one and now I’m getting an “error updating GPT” message whenever I try to update.

I’ve been running with 20 documents for a while ago and some of them are quite extensive, but this file is much less dense than many others which work fine. I can also create a new GPT with that file so it’s nothing to do with the content.

Does GPT have a general limit to the total size of all its documents? Such that updating this file would now cause a problem? It’s only the difference of maybe 500kb and a file under a meg in a set of files at about 15 megs total.

I’m worried about removing files and adding them again because I don’t want to create a version of the GPT where I’m locked out of the density of files I’d added to him.

The version prior to the update, you know, if that’s the best I can get from him that’s what I’ll accept but it just doesn’t seem obvious why I should be facing this issue.

I have about four other GPTs that won’t update for no clear reason. Similar issue… Add 18-20 docs and suddenly won’t update, even though I have many more I made around the same time from which I get no troubles for having similar amounts of docs.
