I have a similar behaviour (hangs) recently, once with a corrupted filesystem, had to force shutdown laptop several times a day. Today when I was in console and not GUI (because the hang happened already during logging in to Xfce and I was lucky to be able to switch via Ctrl-Alt-F1 to console, I finally saw the Kernel Oops.
Using Mint 19.3 on HP ProBook 6470b/179B BIOS 68ICF Ver F.73 08/07/2018
CPU Intel(R) Core(TM) i5-3340M CPU @ 2.70GHz
Message on the console when system crashed:
BUG: unable to handle kernel paging request at 000000d4b2d9323e
IP: __handle_mm_fault+0x5b/0xff0
PGD 0 P4D 0
Oops: 0000 [#2] SMP PTI
... entire trace I have in a photo of the screen if necessary.
Laptop was rock stable until recently and it appears the previous 4.15.0-147-generic #151-Ubuntu SMP kernel is OK, currently running at this kernel and decided to remove for now the probably problematic kernel and block auto-updates to it.
