After 1y+ of smooth operation... system degrades and crashes

It may have started after a recent update. I'm currently on:

• Distro: Zorin OS
• Kernel 7.0.0-28-generic
• Nvidia Driver Version: 580.173.02
• Desktop PC, AMD CPU, Nvidia 3070
• Default Gnome DE
• Checked the health and usage % of the NVME drive and everything looks healthy

The system starts degrading, often within 5 minutes of waking it up from a suspended session.

• mouse pointer works but keyboard input (mostly) not
• apps stop responding
• Terminal or system monitor can't be launched
• App icons in task bar disappear
• Icons at the bottom of Start menu disappear (power, lock, session...)
• Ends in black screen
  • Once I got a "systemd-journald[...] Failed to write entry to /var/log/journal/... ignoring: Input/output error" message repeating over and over
• Force shut down with hardware button

Has any of you experienced something like this recently? Is there something I else I can check/share with you in hopes to figure out what is going on?

Thank you in advance
