Comment 6 for bug 2060920

I *think* you may have run into the issue with the installer crashing on the timezone selection screen (which is directly after network selection and which had a fatal issue with an out of date library; LP: #1987454). That issue is now corrected on the current daily (from 4/22 which I'm ISO testing as a release candidate), and I'm unable to replicate a full crash when attempting to connect to a WPA3 AP. Rather, it just sits there and fails to connect to the AP.

Incidentally, we do now have the firmware blobs that *allegedly* support WPA3 on the BCM43455 (used on the 3A+, 3B+, 4B, and 5) but apparently they only work with WPA3 under iwd (not wpa_supplicant) currently.
