I have no idea, but there are a couple ways us Pixel 5 guys can test this.
One way is to just reflash unmodified vbmeta and boot, then attempt to disable verity and verification, and flash the patched boot image again.
The other way, which I feel would be more appropriate, would be to start with a clean install of Android 12, set up the device, then attempt to disable verity/verification and flash the patched image.
It sucks not knowing exactly what is causing our data corruption issue. For some odd reason it seems like the only way to root on Android 12 is to have a clean install...BUT there's no saying how old that original clean install can be.
