How can I export Image Crop configuration with an Image Style for custom module?
Please see: https://www.drupal.org/project/drupal/issues/2247257

The uuid under the effects array is used as a "unique ID" for the effect.

Seems technically it "works as designed", but as you can see from the linked project task, there is talk about if it's designed correctly.

Fortunately, the uuid under the effects array is scoped to that effects namespace, so it is safe to have the same uuid under any effects array you have regardless of the image style.

Example:

langcode: en
status: true
dependencies: {  }
name: 136x91
label: '(35mm Film 96dpi) 136 x 91'
effects:
  42cf8d4f-246c-4a6d-835f-868e5bcea297:
    uuid: 1cfec298-8620-4749-b100-ccb6c4500779 // &lt;- could be any uuid value
    id: image_scale_and_crop
    weight: 35
    data:
      width: 136
      height: 91
      anchor: center-center


Just note that if you have two effects in one image style, they will each need a unique uuid key.

Example:

langcode: en
status: true
dependencies: {  }
name: teaser_290x163
label: 'Teaser Image 290 x 163'
effects:
  bdd99645-b55a-47b4-9337-89453c12658e:
    uuid: 1cfec298-8620-4749-b100-ccb6c4500779 // &lt;- same as above
    id: image_scale_and_crop
    weight: 1
    data:
      width: 290
      height: 163
  4f4a1ff4-f127-4693-af57-d8f0cf3c9de0:
    uuid: 1cfec298-8620-4749-b100-ccb6c4500780 // &lt;- needs to be unique
    id: image_resize
    weight: 2
    data:
      width: 290
      height: 163


So remove the uuid from the first line for the image style itself, but leave the uuid under the effects array when you export.
