Fatal errors while getting metadata

[melindakraft]

I am trying to export a large list of content from our KMC. It seems to be failing during the get metadata process, and while the error claims that there is a deprecated simplexml_load_string, I think it has more to do with the size of the dataset because it runs fine with a small dataset. Here's the error from terminal - running on Mac 14.5 and php 8.3.1

Getting metadata for the entries...
