Could you please print which class/field is causing the invalid struct access? I'd rather find the source of the issue, than to implement a workaround that might yield potentially faulty results. I still appreciate that included stacktrace and the PR.

[0000FC78] {0x27416bddff0} LocTextBlock NewGameEmbark.NewGameEmbark_C.WidgetTree.ResearchCostString
[0000FC6F] {0x27416bd7180} LocTextBlock NewGameEmbark.NewGameEmbark_C.WidgetTree.CropFertilityString

should be these two

[0000FC78] {0x27416bddff0} LocTextBlock NewGameEmbark.NewGameEmbark_C.WidgetTree.ResearchCostString [0000FC6F] {0x27416bd7180} LocTextBlock NewGameEmbark.NewGameEmbark_C.WidgetTree.CropFertilityString should be these two

So is that the class it tries to find, the property that's being iterated, the class that's being iterated? You need to give me some context of what you're printing.

Looks like the cause of the problem is that the class LocTextBlock was not parsed correctly. But also I didn't find any dumped class with these properties (ResearchCostString, CropFertilityString).

Printed same lines as from GObjects-Dump-WithProperties.txt with same GetIndex() and GetFullName()
I can print something else if you tell me what you need.
