Pls read the docs.
IPv1.5.9 does maximum support PHP 7.2.x
IPv1.5.10 does maximum support PHP 7.3.x

Pls switch for Version 1.5.9 to PHP 7.2
After the Update to IP v1.5.10 you can switch to PHP 7.3

The next release anyway will support PHP 7.4 but for now pls stick with PHP 7.2 as it can run all of the latest versions without problems.
