Moved to the dev branch 2.0.x. Thank you so much

Would it be possible to tag 2.0.12 with this fix?

🌱 Plan for 2.0.12 Release of Block Class Active

Issue patch from merge, use before release.

Patch #13 is not working with
PHP: 8.1.0
Drupal: 10.2
Block Class: 2.0.x

So adding new patch which worked for me.

Confirmed patch from #14 works properly

PHP 8.1
Drupal 10.3.1
Block Class 2.0.11

Thanks visway12

We were experiencing this issue prior to updating to Block Class 2.0.12
While updating resolved the error, block classes are still no longer visible/usable.

Drupal: 10.3.5
PHP: 8.3.11
Block Class: 2.0.12
