Error with block webform

It seems to work in the project we built this module for. Do you get any specific javascript errors in your browser's inspector console?

@Ruuds The block does not hide and the button does not appear either

If that's the case, the block_button_modal_block_view_alter or the template_preprocess_block_button_modal_block method probably doesn't get called.

As i cannot reproduce the issue, maybe you can help me out identifying the issue. If you replace the contents of the block_button_modal.module file with https://gist.github.com/ruuds/5163d887431862d83f9f6d4d3a592939 (changed lines are 32, 36 and 56), what output do you get?

The lines

block_button_modal checkpoint 1
block_button_modal checkpoint 2
block_button_modal checkpoint 3

should appear somewhere on your page.

@Ruuds Thanks for answering, I copied the code as you indicated and I see that it only printed block_button_modal checkpoint 1, as seen in the picture https://postimg.cc/ykBCDSVm.
I want to clarify something that may have to do with it. I am using a theme from scratch using the starterkit generator. Also, my characteristics are the following:
- Drupal 9.5.8
- MySQL 5.7.41
- PHP 7.4.33
- Apache 2.4.52

Note I use php 7.4.33 because there are still several modules that were not updated to PHP 8 maybe that has something to do with it

If only 'checkpoint 1' is shown, it means that the block_button_modal is not enabled for the webform block. As it works correctly in my situation i am wondering if you are using any additional block-related modules? It seems, for example, that the block_class module prevented saving of third party settings (which is used to determine if block_button_modal is enabled or no) in an older version. See https://www.drupal.org/project/block_class/issues/3299925 →

Please try updating to 1.1.1 and let me know if that works.
