My WIFI on my ASUS RT-AX53U just Broke

Hello,
Today my wireless connection just broke down. It was still working this morning (like the last few months) without me changing anything and then it was gone.
When I looked in my configuration, I saw that my devices are no longer active and the LEDs for WIFI are no longer flashing.


I then updated to the 23.05.3 firmware. but that didn't change anything. when I then reset all the settings, the wireless Setting is no longer displayed. (It's just gone)

Unfortunately I am not very familiar with openWRT, does anyone have any idea why this might be the case or how I can fix it?
