@Geez I'm pretty confident that I've found the issue, though it raises a new concern.

@Geez All devices on the network require a static (private) IP by default. I can confirm that no devices are using a private IP that has been issued to another device.

For context on the network setup, I am using Ubiquiti UniFi and the configuration is pretty basic.

Thanks for following up @Geez !

@Geez Any ideas on what could be the issue here? Checking back in today, and DayZ on PS5 remains completely unplayable due to the BIOS error and the errors noted above.

As a means to remove corrupted files from the mix, I and others deleted DayZ from each Playstation 5, rebooted, and then reinstalled DayZ.
