Ok, from my experimenting with getting existing code into a duplicated IPlugEffectCairoGraphics project I found my project was crashing AU Validation when I tried to update the resource.h PLUG_MFR and BUNDLE_MFR etc fields to my own company name. I used the W-DLicate App, but as it doesn't update the these name fields I tried to do it by hand... this didn't go well!
I found this handy cheat-sheet on how to fill in the resource.h, but it's still crashing validation, so wondering if there's somewhere I've missed a couple out?

I believe I had these issues in WDL-OLI as well.
Edit - I've deleted the audio unit cache between compiles as well in case the renaming corrupted it, but that didn't help.
