Cannot access Block, Field UI, Views UI config pages when Config Enforce Devel is enabled

Adding these two lines to config_enforce_devel_config_enforce_form_denylist works around the problem. Not ideal, but here's a patch to get around the issue.

    'block_admin_display_form',
    'block_form',

Changing the title to reflect the more widespread set of errors. Also upping the priority because this is completely breaking things.

As far as I can tell, this change was probably introduced as part of #config_target in ConfigFormBase: using validation constraints for editing simple config → . After some tinkering, I think the fact that we're extending ConfigFormBase for the embedded enforce form is the root cause that's causing Drupal core to attempt to call that method that's in the fatal error; basically, since the embedded enforce form now looks like a config form, it's making Drupal core treat the parent form - e.g. the block layout form, field UI, etc. - as ConfigFormBase even though they themselves only extend FormBase.

After composer update and the update of core/module versions..
Started to get WSOD errors on the block page, add/edit fields, etc..

Tried the patch here: https://www.drupal.org/project/config_enforce_devel/issues/3424770#comme... 🐛 Fix WSOD when visiting the config_enforce page Needs review . but it did't resolved the issue.

Then updated composer to use the dev version -- as that's the one that has the merge https://git.drupalcode.org/project/config_enforce_devel/-/merge_requests...
composer require 'drupal/config_enforce_devel:1.0.x-dev@dev'

Going to the dev version resolved all the error happening in multiple pages.

I've merged the associated MR here, and will cut a new release shortly. Thanks for the fix @Ambient.Impact, and the validation the patch helps, @Blanca.Esqueda!
