Photoshop Export Layers to Files Fast - crashing Photoshop.

[EdwHow]

PS 23.5.1 on Windows 11 Pro 10.0.22000.
2 of 3 Files I worked on for 6 months without issue crashes PS when I started script. 1 worked fine.
Big files 8000+x7000+. Hundreds of layers in 20+ groups.
Failed - shortening names of layers/groups,
Failed - changing file dimensions slightly.
Failed - reducing layers and groups eventually down to 2 layers in 1 group.
(file attached).

Succeeded - Dragging and dropping all layers and groups into a new file of exact same dimensions.
