I have booted on 6.3 and 6.4, both with the same result.
If I boot with 6.1 the prompt for entering the luks passphrase is there and
I can use the machine.
Getting 6.3 using snapshot.debian.org is possible, but also needs some changes on
the packages config. I managed, but this needs additional work to get it right.
I have filed a bug against udev and later vs. nvidia-driver.
Purging nvidia stuff and using nouveau I could also run with 6.3 o 6.4.
After 6.5 came into debian I have tried again with nvidia and it works again.
So for 6.3 and 6.4 I basically couldn't use nvidia. Not sure about 6.2 as this is
not available on debian.
To diagnose the issue I always booted into debian live.
Mounted the encrypted luks partition and modified the initramfs-tools, generated
new initrd-Images and try again and again.
Getting early netconsole to work and fiddling with the initramfs stuff was not so easy for me.
I know that there can be issues running sid, but this was a lot harder than expected.
You have a working system, do an upgrade and boom this system cannot even boot up.
Using debug=x (or whatever value, it doesn't matter) and netconsole=... helped to remedy
this problem.
Sigh, Thomas

You should blacklist usb devices not found during boot and still listed
with udevadm. You can also try to unplug all usb devices and plug them
one by one to find which hangs.
Do you try to boot on another kernel or a debian live ?
