I'm new to proxmox, installed 9.1.4 on a ThinkCentre M715q Tiny off ebay.

The PC runs fine and passes ram and cpu stress tests without issue.

Currently I am only running a Crafty Controller LXC installed with the community script to test out proxmox and learn as well as to host a minecraft server for friends, this works well until the PC freezes requiring a physical reboot.
I have verified the freeze by leaving a display & keyboard connected and checking when its become unreachable, when the freeze happens it's entirely unresponsive.

The only error I am seeing around the freeze time is:
Code:

Hi,

does the freezing happen when the server is idling?
It could be related to a sleep state that the AMD Ryzen 5 2400GE enters when idling.

Try to disable it in the BIOS. Look for something relating to 'Power Supply Idle Control', 'C6', or something similar.
It might be hidden in some sub-menu in the advanced section.

Have a look at this thread as well it seems like this is what you are experiencing:
Server hangs for no apparent reason (AMD Ryzen)

Hope this helps
