The issue is caused by the Nvidia driver upgrades failing to remove newly obsolete links in these directories:

/etc/systemd/system/systemd-suspend.service.requires/
/etc/systemd/system/systemd-hibernate.service.requires/

The entries to remove should look like this:

nvidia-hibernate.service -> /lib/systemd/system/nvidia-hibernate.service
nvidia-resume.service -> /lib/systemd/system/nvidia-resume.service

Follow these steps:

1. Make sure the Nvidia related symlinks are really broken
2. Delete the broken Nvidia related symlinks in both directories and the issue should resolve itself

This issue only affected my Ubuntu laptop systems. My Ubuntu desktops did not have these symlinks installed.

The broken symlinks cause X11 sddm to crash when the system resumes from hibernation or suspension.

There is a bug related to it posted here on the Ubuntu bug site.
