If this issue only happens during the upgrade or before the system is rebooted, I don't think there is anything we can or should do in the Debian packaging for this. There simply are changes sometimes that require rebooting or at least restarting affected apps after applying an upgrade. In particular, we will not support upgrading from Debian 12 to Debian 13 without a reboot after the upgrade. Thank you, Jeremy Bícha
