python3 generate.py not responding

No errors, no nothing, it just hangs... unless I Ctrl + C, in which case this happens

KeyboardInterrupt

I have 3 layers - main, border, motif. filenames are main (1).png... main (16).png, border (1).png ... border (8).png, motif (1).png ... motif (6).png. weights for main, border and motif are 100 each in total.

{
    "main": [
        {
            "name": "main",
            "fileName": "main (1).png",
            "weight": 6
        },
.
.
.
        {
            "name": "main",
            "fileName": "main (16).png",
            "weight": 7
        },
    ],
    "border": [
        {
            "name": "border",
            "fileName": "border (1).png",
            "weight": 12
        },
.
.
.
        {
            "name": "border",
            "fileName": "border (8).png",
            "weight": 13
        },
    ],
   "motif": [
        {
            "name": "motif",
            "fileName": "motif (1).png",
            "weight": 16
        },
.
.
.
        {
            "name": "motif",
            "fileName": "motif (6).png",
            "weight": 17
        },
    ]
}

And .env is

URL_TO_IMAGE=test_col1
NEW_URL_TO_IMAGE=new_test_col1

COLLECTION_SIZE=768
NAME=test_col1
PATH_TO_JSON=./layers.json
PATH_TO_LAYERS=./layers
PATH_TO_IMAGES=./images
PATH_TO_METADATA=./metadata

PATH_TO_RESIZED_IMAGES=./images-resized
OUTPUT_IMAGE_SIZE_X=576
OUTPUT_IMAGE_SIZE_Y=576

Images are 491x93 px, around 90kb to 400kb in size. Even renaming all to main_10.png doesn't work. Where did I do wrong?

Thanks a lot!
