I resolved the issue by downloading/flashing the rpi-boot-eeprom-recovery-2022-04-26-vl805-000138a1 image from github. Any image newer than this seemed to get the same red screen... but then a fresh bullseye64 image ran the automatic eeprom updater, and that successfully got me to the latest "default" bootloader.
I closed the github issue and we can consider this one closed, too. The workaround is to install an intermediate bootloader version. I guess it's just failing on the huge single-step update.
