I'm checking the example file and it looks damaged. The initial crash is because there is a defined Palette with colors, but the color pointers are damaged. This looks an old version Palette.

The problem was in do_versions_fix_annotations() in the second loop: LISTBASE_FOREACH (bGPDpalettecolor *, palcolor, &palette->colors) {

I have checked removing this crash and then I get a totally different assert error.

BLI_assert failed: D:\MyBlender\BlenderDEV\blender\source\blender\makesrna\intern\rna_access.c:5732, rna_idp_path(), at '!RNA_pointer_is_null(&child_ptr)'

@Philipp Oeser (lichtwerk) any idea?
