Router unresponsive after reboot

I have a cAP AC that I’m trying to get configured. After spending hours yesterday configuring and setting up scripts and WireGuard etc I took a backup and performed a reboot. The router did not come back, no DHCP, no wifi. I set a static address in same subnet and still no ssh or web access. I performed a factory reset and regained access and attempted to restore the backup, it rebooted and again no access.

Tonight I manually reconfigured the router and took another backup, rebooted and same issue.

Because there’s no serial console port on the cAP AC I have no way of looking at boot sequence.

# nov/28/2020 00:43:52 by RouterOS 7.1beta3
# software id = 50RA-6BBJ
#
# model = RBcAPGi-5acD2nD
# serial number = BECD0C73D111

From a fresh factory reset I have issued only the commands below to perform bare bones configuration from the default config. Was working fine prior to the reboot.
