Download doesn't work with Drupal 10.1.x (max execution time exceeded)

Thank you for reporting the bug, I'm sorry you've ran into this problem.

FYI please don't repeat the issue title in the tags, that just adds noise, please only assign the issue to yourself if you're actively working on it, and please be cautious of the HTML tags from the issue summary template so that you don't end up writing the entire message as a H3 heading.

I also have this issue. In my case, I'm using Backup Migrate 5.0.3., Drupal 9.5.10., PhP 8.2.3., Apache 2.4.56 e MySQL 5.7.36, running in Wampserver 3.3.31 (64bit). The backup never completes.

In this same server I also have two other sites running: one in Drupal 7.98, with Backup Migrate 7.x-3.10 and other in Drupal 10.1.1 and Backup Migrate 5.0.3 (this one is for testing purposes, it is empty, but has several modules installed.). In this last cases, everything is working perfectly.
