Seems like my Nighthawk AX6 6-Stream AX5200 WiFi Router (RAX48) keeps rebooting continuously

My AX5200 WiFi Router (RAX48) was working without a glitch until last month when I unplugged the router for a month as I went overseas. When I returned, I could not connect to the router through WLAN or LAN. The power light keeps flipping between orange and white in every 10seconds. I tried resetting the router, toggling the on/off button, changing power outlet etc., but nothing works.

When I connect my Mac to the router with a LAN cable, what I see is

1. Power light is orange and LAN 1 light is white

2. After a few seconds, power light becomes while and LAN 1 light goes off

3. Keeps repeating 1 & 2 in every few seconds

The 2.4 and 5 GHz buttons never lit.

Is it an outdated firmware issue? If so, how to resolve this as I can't get into the router?

Edit: Purchased the router brand new in November 2020.

When the power light is blinging orange or white, it tends to indicate a boot/corrupt/firmware issue. 

You've tried the reset. 

You can try recovering it with tftp or nmrpflash.
are you on windows? if so, follow this guide
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
just make sure you enable tftp
https://www.thewindowsclub.com/enable-tftp-windows-10

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.
