Random object gets printed to the console and python freezes

The problem

Console randomly prints an object
The object in question:
{"r": 23, "c": "jsi", "p": 1, "action": "call", "ffid": 11, "key": "", "args": [12, {"ffid": 34}, {"ffid": 35}]}
This object can very each run, sometimes the problem doesn't even happen!
After this is printed python gets held up and after 100000ms pythonia throws an error:

node:internal/event_target:1011
 process.nextTick(() => { throw err; });
                          ^
Error: Attempt to access '__call__' failed. Python didn't respond in time (100000ms), look above for any Python errors. If no errors, the API call hung.

I think maybe this issue might also be related to #68 ?
I tried to debug it on my own bug have no clue what the problem is or where to even begin looking

Code

Bit of my code:

var images = await (await main.__call__$(prompt, {
    negative_prompt: negPrompt,
    callback: progress,
    guidance_scale: scale,
    num_inference_steps: steps,
    num_images_per_prompt: images,
    height: height,
    width: width
})).images

"Main" is from a StableDiffusionPipeline pretrained pipe AKA:

const pipe = await dif.StableDiffusionPipeline.from_pretrained$(moduleToLoad, { torch_dtype: await torch.float16 })
const main = await pipe.to("cuda")

Dif being the diffusers and torch being torch

after doing some debug it looks like the callback: progress is causing the issue, Fix is to remove it but it would be nice to have the callback!

if it's the same as #68, then putting a reference to your callback somewhere in Python should help, as then it won't be removed by Python's garbage collector. I guess that would be a bug in the bridge but such a hack might work to go around it before it's fixed.
