Just for documenting the issue for others:

tested with r18155 (2021-nov-21) the wifi interface
does not come up in adhoc mode when HT20 is enabled.

uci set wireless.radio0.htmode=HT20
wifi
=> not working

uci del wireless.radio0.htmode
wifi
=> OK/working

The relevent log collected with /lib/netifd/wireless/mac80211.sh
is here, it fails at the last 'iw' call:

without HT20 mode enabled:

[...]
rc:0 | iw dev wlan0 set type ibss
rc:0 | iw dev wlan0 ibss join ffintern.2GHz 2432 fixed-freq 02:ca:ff:ee:ba:be beacon-interval 250 mcast-rate 6

removing mcast-rate or beacon-interval does not change the behavior.

the driver itself seems to report HT20 capabilities:
