Your memory looks strange.

Ryzen processors can have RAM compatibility issues.

Processor: Ryzen 3 3200G
Mobo: MSI A320M pro max
Ram: 16 GB (2x8GB Gskill Ripjaws 2400 MHZ)
product: F4-2400C15-8GVR

Your BIOS is current at 2.80.

Your RAM isn't on the compatible list as seen on https://msi.com/Motherboard/support/A320M-A-PRO-MAX/#support-mem-18.

free -h reports only 13G out of 16G installed.

Go to https://www.memtest86.com/ and download/run their free memtest to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take many hours to complete.

Update #1:

memtest fails. Remove one 8G DIMM and rerun memtest. Then test the other one. Possible bad motherboard, or bad (or not compatible) DIMM.

Update #2:

One DIMM passed memtest. One DIMM failed memtest. Will try to get a warranty replacement and re-run memtest.
