Tested the latest respin of the 22.04.2 ISO as of now. UEFI + Secure Boot, Broadcom WiFi, used the en-GB locale. Enrolled a MOK at installation time. Installation successful, rebooted, enrolled a MOK, rebooted again, got a working desktop. WiFi did not work upon reboot (bug 2008120) but that's a different bug. I can confirm that the crash mentioned here has been fixed.
