xdg_desktop_portal_gtk crashing while trying to access unreadable region

[Lucas]

Description: Ubuntu 24.04 LTS
Release: 24.04

xdg-desktop-portal-gtk:
  Installed: 1.15.1-1build2
  Candidate: 1.15.1-1build2
  Version table:
 *** 1.15.1-1build2 500
        500 http://de.archive.ubuntu.com/ubuntu noble/main amd64 Packages
        100 /var/lib/dpkg/status

expected to happen: no crashes

what happened instead: crashes
updated system with sudo apt-get update and the sudo apt-get upgrade. since then xdg-desktop-portal-gtk crashes while trying to access unreadable region, even when restarting. always produces exactly two internal errors to pop up (seems to be standard for ubuntu). According to stacktrace "No symbol table info available" so not helpful for debugging purposes

Full crash report is available as attachment
