All of a sudden a cache tag was added to my env.php which made made my Magento 2.4.4 crash.
I cannot run cache flush or anything without getting the following error:
Notice: Undefined index: frontend in
/var/www/magento2/vendor/magento/framework/App/Cache/Frontend/Pool.php on line 90
When I remove the cache-tag, everything works are normal again.
How could this tag appear out of nowhere??
Is this a hack?
