9.5.8 updates broke twig templating for Admin theme

Created on 24 April 2023, over 1 year ago

Problem/Motivation

I am getting this error and a WSOD when trying to edit or add content after updating last week with the latest security patch:

Twig\Error\LoaderError: Template "__TwigTemplate_c8e9244b262a7baf36e943514a9035eb798d052b64e4bd586b2545bc29c153bb" is not defined. in Twig\Loader\ChainLoader->getCacheKey() (line 98 of /var/www/html/drupal/vendor/twig/twig/src/Loader/ChainLoader.php)

Steps to reproduce

I have 9.5.8 installed and Adminimal admin theme. I have tried other themes - Claro, Gin, etc. and I get the same results even after clearing cache.

Proposed resolution

Don't know - I see something about a change in twig from 2.15.2 to 2.15.3 that looks at template names differently, but I'm not a programmer so not sure. I tried 2.15.4 and the latest twig dev versions and and all had the same results.
