Monterey Beta Bricking 16-inch M1 Pro MacBook Pro

Would love to get some insight from anybody else that may have experienced this.

I bought a 16-inch M1 Pro MacBook Pro in January. Installed the Monterey beta on it at the end of January. In February, I spilled a full cup of coffee next to it and brought it in for Apple Care repair.

They replaced nearly everything- from the logic board to the batteries to both cases and fans.

When I was restoring my time machine backup, migration assistant advised updating to the Monterey beta since that's what OS my backup used.

Accepting this prompt within migration assistant restarted the machine but did not complete the update. So I tried to update to the Monterey beta from within system preferences. This resulted in a boot loop and effectively bricked the computer.

I restored using Apple Configurator and DFU mode and have tried every possible permutation of updating to the Monterey beta only to receive the same result.

Does anybody know what could be causing this?

Apple released 12.3.1 today which allegedly addresses this issue.

My MacBook Pro is still at the repair shop waiting for a second replacement logic board.

Does anybody who was experiencing this issue have theirs handy to test and verify this?

Did any of you above check to see under about this Mac if under serial number was showing unavailable? If so then the Apple Store could have failed to flash the replacement logic board with existing serial number which likely caused issues installing software update?

I am also assuming that's why Apple has not released any new betas due to complaints of logic board replacments causing bricked MacBooks?

I just updated to 12.3.1 A-OK, so it seems that they've patched the bug!

Should I wait? 12.3.1 update still fails for my M1 Max MBP 16 inch 2021. I am afraid to try safe mode again.
