I don't know whether this is the issue in your case, but I found when setting the default Python flavour to 3.10 myself I would get the same problems: ports would not build due to an "unknown" flavour.

I discovered that in some cases, "USES= ... python:<version range>" in a port Makefile would make it impossible to build with the default flavour I had set in /etc/make.conf.  A case in point: I wanted to build sysutils/py-salt via Poudriere with a default Python flavour of 3.10.  It failed.  Looking in the Makefile, I saw "USES= cpe python:3.6-3.9".  Most other ports tend to have "... python:3.6+", but this one said it only worked with 3.6 to 3.9.  Hence, trying to build it with 3.10 failed.

I knew that version of py-salt would build under 3.10, so ultimately (after carrying my own local change to the Makefile for a while) submitted a Bugzilla asking for it to be changed to "USES= cpe python:3.6-3.10", which solved the building problem.

So, you may have some similar Python ports or dependent ports that specify they aren't compatible with Python 3.11, and that is causing the warnings and errors.
