Your device appears to be an international global hardware model because there is no chinese writing on the shipping box and your photo shows SKU:DVB4230GL. Did you flash chinese v2 firmware to debrick the device?

Please post a photo of the bottom of the actual router.

Is this router brand new ?

Updated: I note from your photo, it shows mtd6: 00100000 00010000 "overlay". The R4AC international model uses mtd6: 00200000 00010000 "overlay" according to:
R4AC international openwrt install instructions.

fwiw, if you have accidentally flashed your international R4AC with chinese v2 firmware, see this post:

fyi, original v3.0.5 international fw download link

Looks like Global/international model to me because there is no chinese writing on the label. Also confirmed by SKU: DVB4230GL part number on the cardboard box.

What firmware was installed when you first took it out of the box?

As suggested in previous post, if you debricked it using chinese v2.x firmware by accident, and therefore converted it to chinese model, perhaps try reinstalling 21.02.3 or 22.03 for Chinese model.
