Archer C60 v3. Weird behaviour sometimes on 5ghz radio

Is my home network. Probably 4 devices on 5G, and maybe 5 more on 2.4. No heavy downloads, but streaming on the android TV.

Today, suddenly the 5ghz radio just went down and then came up, there was no heavy downloading, just browsing pages.

Is just a dumb AP, so no routing or firewall, but the stack mentions the firewall for some reason, which is odd since it is disabled.

I found this stack trace, still trying to figure out what it means:
