 WordPress 5.8.1
 PHP 8.0.10
 All plugins disabled
 Default Theme

 I upgraded our PHP to 8.0.10 and WordPress is unable to generate
 thumbnails for images I upload into the media library. I tried a thumbnail
 regenerating plugin and that did not work either. I tried PHP 8.0.3 and it
 didn't work. I dropped the PHP version down to 7.4.11 and it started
 working again.

 I am not the only person with this problem:
