Realport 1.9.42-1 on Ubuntu 22.04.4 (5.15.0-113-generic) Symlinks not created

Yesterday, I built 40002086_AC_debiansourcepkg against a new Ubuntu 22.04.4 (5.15.0-112-generic) server and everything seemed fine with running a TS8. Devices and symlinks got created as expected.

Then I ran an upgrade of Ubuntu to get latest patches and in upgraded to 5.15.0-113-generic.
So I rebuilt the digi package and removed and reinstalled.
Now the long-winded /dev/tty_dgrp_XX_[0-9] devices get created, but not the short symlinks like /dev/ttyXX[0-9]

This a udev based system, but i don’t see any specific digi rules in the /etc/udev/rules.d directory. (I saw that referenced in another thread).

There is nothing I see in /var/log/syslog or elsewhere. Starting and stopping the daemon doesn’t have any effect.

I can obviously play games and put my own script in to create the symlinks. But I’m curious if anything similar has happened on upgrades before?
Should there still be a /etc/udev/rules.d/10-{whatever} rule for the digi drivers?

Per some prior threads, I investigated doing custom udev rules.
I created a 10-dgrp.rules as follows:

KERNEL==“tty_dgrp*”, PROGRAM=“/usr/bin/dgrp_udev %k”, SYMLINK=“%c”, GROUP=“root”, MODE=“0666”, OPTIONS=“last_rule”

Seems to work fine.
