Why might the bootstrap modal window not work if everything is done correctly?

Question

PHP

I implemented a modal window from bootstrap, scripts and everything else is present, before the window worked and suddenly stopped, it didn’t move an inch in 5 hours. Maybe someone faced such a problem.

Tested on the window in other places, the window immediately pops up without a call, but it's still not visible, it's somewhere outside the browser window.

And if you try, instead of:
id="myModal'{$a_id}'"
