I would disable ImageMagick, after doing some research on it I found several instances of people getting odd errors because of it. More than likely caused by your specific host or hosting environment implementation of ImageMagick. Although I did not find your exact error.

Although this could also have something to do with another plugin.
https://developer.wordpress.org/reference/hooks/wp_image_editors-9/
add_filter('wp_image_editors', 'disable_imagemagick');
function imagemagick($editor) {
return array('WP_Image_Editor_GD');
}
That or contact your host to see if they can help.
