File is not valid on element field_media_image[0][image_crop]

I Have the same problem, after update to drupal 8.9.1:

Test 1:
drupal/image_widget_crop 2.3.0
drupal/crop 2.1.0
drupal 8.9.1

test 2:
drupal/crop 2.2.0
drupal/core 8.9.1
drupal/image_widget_crop 2.4.0
drupal 8.9.1

I updated drupal and put the code on a new server with same same php7.2 version
This worked before (same like test1):
drupal/crop 2.1.0
drupal/image_widget_crop 2.3.0
drupal/core: 8.8.7

I got the same error.
Any ideas what i has to check?

I'm also facing the same issue did u got any solution for this issue

We also encountered the same issue after upgrading our project to Drupal 10. We would appreciate it if someone could look into this, thanks in advance!

We had the same problem in our dev environment. The issue was, that the original image was not available. After stage_file_proxy downloaded it properly, the cropping did work as expected.
