I updated the dbus from "experimental" (from 1.12 to 1.13), and the problem indeed went for me as well.
I retried with a clean installation from - https://cdimage.debian.org/cdimage/ports/current/debian-11.0.0-alpha-NETINST-1.iso - https://cdimage.debian.org/cdimage/ports/debian-installer/2021-10-20/alpha/debian-installer-images_20211020_alpha.tar.gz Unaligned trap with the standard dbus (1.12) and nothing after upgrading it from experimental to 1.13 and rebooting. Best regards, Anton Kochkov.
