Hey Celine,
Sure, I tried to recreate it in a stress test and I was successful in remaking the issue, just a few things I did which may or may not be relevant to the issue is its parent size is set to 8k (I turned it down so it wont crash on you on open), I turned off specular on the output, and its a very heavy scene. it only saves the non-core outputs (like diffuse, normal, height, gloss) in this case it only saved the outputs named "output_#"
hopefully that helps.
