Can't save Custom GPT with knowledge files

I can’t seem to publish my GPT if i add any knowledge files. I get various errors but most often “Error saving GPT”

It’s odd because i can save the GPT without any knowledge files in production, however in playground I can save with 18 files with full retrieval.
