I removed snapd completely which did nothing.

Here are new logs:
systemd-analyze blame:
systemd-analyze critical-chain:

I should also note that leaving the system untouched does not result in it booting: I must
provide a source of entropy, otherwise it just stays stuck. In both of the dmesgs I've given, I
manually provided entropy to the system after about 5 minutes of waiting.

Also, regardless of what's hanging on CRNG init, CRNG should be able to init on its own in a timely
manner without the need for user-provided entropy. Userspace was working fine before the recent CRNG
kernel changes, so I don't think this is a userspace bug.
