Thank you for your response! I was able to create logs using journalctl, but didn’t seem to find any messages regarding the shutdown process. 
Sadly, the issue is difficult to replicate, since it doesn’t happen every time. Is there a specific command that I should use to only receive logs from the shutdown process, or should I use journalctl --since=?
I found that another user has a similar issue, and I think our common denominator is the Nvidia hardware.
Unfortunately, Nvidia GPU is the sole GPU I have on this machine, so I can’t switch to integrated graphics and see it it helps.
Thank you again for your help!
