Why doesn't OpenServer want to work with php 5.6 and Apache 2.4?

Question

open server

Started working with OS and PHP 5.6 (early summer 2018). Then it was required to pass to 7.2. Now, in October 2018, php 5.6 is needed again, but openserver has ceased to be friends with it. I tried to completely reinstall - it did not help ... 7.2 works, but 5.6 does not want to.

Aggressive mode does not help. Xs what can be, help, what options can there be?
Apache 2.4 is used, I don't understand why it crashes.
