i switched my Friotzbox wlan to WPA2(CCMP) (so no WPA3) ... and the laptop now connects over wifi with dirks last wpa_supplicant.
So there is some WPA3 fishyness.
The Fritz!box 7430 has a a PMF setting
"Unterstützung für geschützte Anmeldungen von WLAN-Geräten (PMF) aktivieren"
which is default enable for WPA3, but can be selectively enabkled for WPA2 only.
