Okay, I just poked around to make a flying head focused prompt for testing and it seems fairly reliable (I am assuming you want a body with flying head), try a low batch count and change one or two things as a time to see if that helps narrow down a cause

For reference I am using the AUTOMATIC1111 stable-diffusion-webui: https://github.com/AUTOMATIC1111/stable-diffusion-webui

Positive Prompt: RAW photo, 1girl,(head_flying:1.4), (pretty female police woman:1.3),(severed_head:1.4), neck_spray,<lora:0iggb5:1.2>, beautiful day, (high detailed skin:1.2), (blood splatter:1.1),(decapitation:1.4), 8k uhd, dslr, soft lighting, high quality, Fujifilm XT3

Negative prompt: (worst quality:1.2), (low quality:1.2), (lowres:1.1), (monochrome:1.1), (weapon_trail:1.4)(greyscale),blurry,easynegative,moasic,low quality,worst quality,bisexual,futa,futanari,insertlow quality, worst quality,ugly,fused fingers, extra fingers, extra toes,malformed hands, mutated hands,mutated fingers, mosaic censoring, (weapon_trail:1.4)
