Divide and conquer – copy half the layers to one PSD, half to another, import. Narrow down what is breaking. Not fun but I’ve done this technique in various
forms for troubleshooting. Just did it with AE to figure out number of comp/pre-comp layers AE handles in a single project before performance hit. FYI, around 5,000 overall although far less in individual comps – those need to be under 100 to keep AE from
bogging down.
