I has the same a couple of days ago and had to downgrade portage from
3.0.20 to 3.0.18, by untarring the binary package to /. However, that
needed python 3.8, so I also had to untar the binary package for that.
Then I re-emerged portage-3.0.18 and python-3.8 and masked
portage-3.0.20. Once I had re-emerged portage-3.0.18, it worked with
python 3.9.

I see that portage 3.0.20-r3 is here now, so I'll try emerging that on
one system and see what happens.
