Hi Daniel,
In my understanding, the crash is not reproducible after my workaround (switching to the nvidia driver), because the nvidia-resume.service is not masked (my theory).
Therefore, I switched back to the Nouveau driver, and I reproduced the problem and collected the system logs as you asked. Now prevboot.txt contains the logs from a clean boot, through the session crash and ends with a (user requested) reboot.
Just for the record, these are the steps to reproduce the bug:
1. Install Ubuntu 21.10 on a laptop(?) with an nvidia GPU
2. Open "Software & Updates" -> "Additional Drivers"
3. Select the latest driver (470)
4. Reboot
5. Login normally on GDM
6. Open "Software & Updates" -> "Additional Drivers"
7. Select "Nouveau display driver" and apply the changes
8. Reboot
9. Login normally on GDM
10. Try to suspend the system
11. You should observe a session crash here
