Question about Modal and Browser Conflict Issue

[kam5263]

When using a modal in Bootstrap, I encounter the following error message in the browser console after clicking the close button:

Blocked aria-hidden on an element because its descendant retained focus. The focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
Element with focus: button
Ancestor with aria-hidden:

Even when I run the sample code provided in the Bootstrap 5.3 documentation (https://getbootstrap.com/docs/5.3/components/modal/#modal-components), the same issue occurs. Could you help me understand the reason behind this error?

Thank you in advance!
