Networking not starting up properly on boot

Seems like my networking has been failing the last few weeks on boot, I realized that its been necessary for me to go into a terminal and running "dhcpcd enp5s0" on every boot lately to get networking to kick into gear.
I can also see that I get a message in the boot terminal saying "Failed to start dhcpcd on enp5s0", but this works just fine when I do it in a terminal once I've booted into arch and XFCE.
The systemd service for dhcpcd is enabled and started as well, so no issue there it seems.

Has there been any recent changes to networking in Arch (I haven't really changed anything in my network settings, so it seems to me this might be some update that broke something).
Is there anything I can do to check this except add "dhcpcd en5s0" to my startup commands?  (don't really want to do this)

Re: Networking not starting up properly on boot

Read your journal and see why the service is failing.

Moving to NC...

Read your journal and see why the service is failing.

I found this in my journal:

Seems like the service fails to open the PID file. Should I try deleting it if it exists, or would there be some other reason why this problem has popped up all of a sudden?
The later part of the journal is from me running "dhcpcd enp5s0" manually in a terminal.
