--- Comment #1 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
This is a known issue.

Both the release notes and the man page state:

https://www.freebsd.org/releases/15.1R/relnotes/#wireless-networking

"There are known issues with certain chipsets"

rtw88.4:

     At least the 8821CE and 8822BE chipsets have trouble associating, which
     seems to be due to the software scan fallback, the chandef emulation, and
     net80211 interactions, along with a 6s timeout observed in the driver.


I will try to get back to this once I am done with some Mediatek bits.
