Comment (by mitogh):

 @adamsilverstein interesting I was not able to face any of those errors
 and the image was uploaded, the problem was that the subsizes where not
 created, my current size limit is 100MB tho, in my setup Imagemagick is
 used to process the images.

 Looking into more detail (specifically into the Imagemagick
 implementation) looks like the problem is because it creates a larger
 image 5 times larger actually than the uploaded image, which for larger
 images like the one from this issue consumes large portion of memory.

 - https://github.com/WordPress/wordpress-develop/blob/trunk/src/wp-
 includes/class-wp-image-editor-imagick.php#L363

 From my point of view, when a large image is uploaded or when the image is
 bigger than the threshold there's no real need/benefit in resampling as
 images are going to be created in smaller sizes instead.

 I can explore a bit more for imagemagick, but just commenting that line of
 code makes the rest of the subsizes work as expected. Maybe some
 additional logic can be added in place to consider the scenario when the
 resampling is not required.
