pyenv mysteriously not working on WSL after Win11 upgrade

I've been using Pyenv happily with WSL and WIN11 forever. Feels like forever. Years. I prefer WSL1 because it is 10x faster for what I use (long story), and I'm still on Ubuntu 18.04 for my WLS1 shell.

I install via the basic "pull and bash" mechanism. I do a clone of the git repo into the usual location in the home directory, execute the path elements to point there, then pyenv init, in my .bash_alises , which has always worked before.

Right around when I upgraded to Windows 11 - probably two weeks ago, when Win11 came through the beta channel (not alpha), I noticed my python version was python2 instead of python3.

Digging in, I see that pyenv is installed properly, still, but when I 'which python' I get '/usr/bin/python', even though I have exec'd the init so the shims should be installed. Either the shims are not getting installed or they are getting removed or overridden?

I've checked every obvious thing I can find, and it just seems like the shims don't install. I've also tried going to a fresh WSL2 install on U20.04. I've looked at the path --- virtualenv was in front, and I removed that.

If I had to guess, I would assume there's some dependancy on the uname, which probably changed. The current one is:
Linux SUPERFLY 4.4.0-22000-Microsoft #1-Microsoft Fri Jun 04 16:28:00 PST 2021 x86_64 x86_64 x86_64 GNU/Linux

I've looked through the various scripts that should install the shims and just don't see anything.

Halp? Next places to look?
