Failed Task and various errors in logs
Similar to How to fix &quot;ambiguous&quot; column error generated when DeleteStaleTemplateCaches is run?

But somewhere, in one of your templates that are using the {% cache %} tag, you're ordering by dateCreated in your template and it should be elements.dateCreated.

The {% cache %} tag has already picked up the invalid Twig code and cached it to the database so whenever the DeleteStaleTemplateCaches task tries to run, it trips up on the invalid Twig.

So after you fix the original error, you'll want to clear your template caches using the Clear Caches tool under settings in the control panel to purge the invalid cached code as well.
