Description

## Environment

| Item | Version |
|------|---------|
| comfy-aimdo | 0.2.14 |
| ComfyUI | 0.20.3 |
| PyTorch | 2.11.0+cu130 |
| CUDA | 13.0 |
| GPU | NVIDIA GeForce RTX 3060 (12 GB VRAM) |
| OS | Windows 11 Build 26200 |

## Description

ComfyUI (portable) crashes repeatedly with a stack overflow in `aimdo.dll`.
The crashes started immediately after comfy-aimdo was installed via a ComfyUI update on 2026-05-09.

## Windows Application Event Log (Event ID 1000)

Faulting application: python.exe (3.13.11150.1013)
Faulting module: aimdo.dll (0.0.0.0, timestamp 0x69ea3089)
Exception code: 0xc00000fd (STATUS_STACK_OVERFLOW)
Fault offset: 0x0000000000006cdc

The crash occurs at the same offset (`0x6cdc`) consistently across all crash instances (6+ times observed).

## Steps to Reproduce

1. Install ComfyUI portable (windows)
2. comfy-aimdo 0.2.14 gets installed automatically
3. Launch ComfyUI → python.exe crashes with stack overflow in aimdo.dll

## Workaround

Renaming `aimdo.dll` to `aimdo.dll.bak` prevents the crash (aimdo is skipped gracefully).

Start by reproducing the crash with comfy-aimdo 0.2.14 in ComfyUI portable on Windows 11 using the listed PyTorch, CUDA, and RTX 3060 environment. Inspect the Windows Application Event Log for the repeated aimdo.dll fault at offset 0x6cdc, then verify that the crash no longer occurs with aimdo.dll enabled while preserving normal startup behavior.
