Hello! Just installed it on my Pixel 6 Pro. I had the same weird behavior of the boot animation stuck for about 3 minutes (instead of the usual 10 seconds).
But the real problem is it doesn't charge anymore. It could just be a coincidence, but it was charging alright before the update and as soon as it was rebooted, charging stopped working. As soon as app optimization is finished, I'm going to shut it down, boot it back up, try to charge it and look at logs. I'll keep you updated. Please let me know if you know for sure that it isn't linked to the upgrade and I should just create a dedicated post on the forum.
