You have missing quotes on line 11.

I tried it on my 3070 (with the smaller settings), and got the same pink result. I also had to change diffusion_model: "portrait_generator" to portrait_generator_v001 to get it to work...

Symmetry off: 

With H symmetry (instead of V), it is also pink.

512x512 finetune (had to use secondary model for size) symmetry_loss_v: true 

Are you using a different model with: diffusion_model: "portrait_generator" That just gives an error for me.

Confirm that reducing the cuts as @iceandstorm above means don't need to use secondary model, and then get same pink result.
