Does the screen freeze completely (e.g. the clock doesn't change)? Magic
SysRq doesn't work? Are you running Chromium by any chance?

I've been experiencing similar hangs, first with an AMD Phenom II processor
and recently with a Ryzen 5 2400G and a X370 motherboard. This morning I
left the computer unattended with Chromium and top open and top showed
Chromium taking 34% of the CPU around the crash time. Then I left the
computer unattended without running Chromium and ran happily for hours.

I might have a go at running Chromium with debug logs to see if I can see
anything unusual.

Reviewing the journal a few crashes ago I saw some Chromium errors
regarding GPU, might be a red herring though.
