Traceback (most recent call last):

ConnectionError: Unknown failure 1The RPi Pico W fails to connect to the WPA3 WLAN network; the handshake also does not appear in the hostapd logs at all (as opposed to handshakes from other devices).
Description
The WiFi has been setup with hostapd using this config:
# Logging config
logger_syslog=0
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=0
# Basic interface config
interface=wlx***********a
country_code=DE
hw_mode=g
ieee80211n=1
ieee80211d=1
channel=5
# Indoor Tasmota Network
ssid=myotherssid
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
ieee80211w=1
wpa_passphrase={{ passphrase.myotherssid }}
ap_isolate=1
# Outdoor WPA3 Network
bss=wlx***********b
ssid=myssid
auth_algs=1
wpa=2
wpa_key_mgmt=SAE
rsn_pairwise=CCMP
ieee80211w=2
wpa_passphrase={{ passphrase.myssid }}
ap_isolate=1Other devices can connect to the WPA3 network myssid without problems.
Additional information
If I change the network config to:
# Outdoor WPA3 Network
bss=wlx***********b
ssid=myssid
auth_algs=1
wpa=2
#wpa_key_mgmt=SAE
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
#ieee80211w=2
ieee80211w=1
wpa_passphrase={{ passphrase.myssid }}
ap_isolate=1the Pi can connect flawlessly too; however as the official board page explicitly mentions WPA3, I think the Pi should be able to connect too.
