Grey Image when generating using NF4

[iamsuper123]

I generated an image using flux and it's completely gray

some information:
model used: flux1_dev_bnb_nf4_v2
python version: 3.10.6
I tried to use the AE.safetensors vae, except I didn't see a vae option box, so instead I went to settings and specified the vae model there, restarted.
COMMANDLINE_ARGS= --upcast-sampling --lowvram --opt-sub-quad-attention

here's the logs:
