Thanks for the heads up on QGIS from conda-forge vs QGIS from osgeow4. I did not do anything to set Anaconda as the default python. In fact, during Anaconda installation, one is asked whether to modify the PATH to include Anaconda and is encouraged to say No. I said no.
I opened osgeo4w shell, ran qgis command, started a python console (which finds ver 3.9.5) from osgeo4w shell, and examined sys.path. As you might have expected, Anaconda python, dll’s, site-packages, win-32\lib all come before QGIS python, site-packages and lib. I’ve tried installing Anaconda first, and QGIS second, as well as QGIS first and Anaconda second. In either scenario, QGIS cannot locate its python modules, and hence, no plugins are available nor can I use GRASS. I’m stumped trying to get the kids to play together nicely!

Have you set Anaconda python to be the default python? I think you shouldn't. Please notice that QGIS on conda-forge is not as feature-rich as the one provided by osgeo4w. There's no GRASS or SAGA, no proprietary drivers to open ECW and other proprietary formats, and so on.

When QGIS starts, it prepends apps\qgis\bin and app\Python39\Scripts to the PATH I started python from the OSGeo4W console. Here’s output of sys.path: ['', 'C:\\ProgramData\\Anaconda3', 'C:\\ProgramData\\Anaconda3\\DLLs', 'C:\\ProgramData\\Anaconda3\\lib', 'C:\\ProgramData\\Anaconda3\\lib\\site-packages', 'C:\\ProgramData\\Anaconda3\\lib\\site-packages\\win32', 'C:\\ProgramData\\Anaconda3\\lib\\site-packages\\win32\\lib', 'C:\\ProgramData\\Anaconda3\\lib\\site-packages\\Pythonwin', 'C:\\Program Files\\QGIS 3.20.3', 'C:\\PROGRA~1\\QGIS32~1.3\\bin\\python39.zip', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\DLLs', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\lib', 'C:\\PROGRA~1\\QGIS32~1.3\\bin', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\lib\\site-packages', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\lib\\site-packages\\win32', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\lib\\site-packages\\win32\\lib', 'C:\\PROGRA~1\\QGIS32~1.3\\apps\\Python39\\lib\\site-packages\\Pythonwin'] Anaconda goes first, before QGIS. I’m not surprised that QGIS can’t find its modules. I think I’ll uninstall QGIS, and reinstall from conda-forge.

Both QGIS and Anaconda write to “Python > path,” though >QGIS entries are first in order. Can you start/stop QGIS from the osgeo4w.bat terminal and check the values of PATH and PYTHONPATH there? Just to be sure that osgeo4w is ONLY pointing to the python versions of osgeo4w (and not tainted by conda's). Also: not only check python but also available QT/sip related environment variables. Another check: (mmm wanted to ask you to check sys.path in python console in QGIS... but THAT you do not have :-) Then: for the osgeo4w.bat terminal start python and in that console: import sys print(sys.path) and check which path's osgeo4w python is seeing/using? (note: you could do the same in the conda environment) Another work around: do not use the osgeo4w QGIS, but the conda QGIS?
