Hi All,
For those who find themselves here in the future, I have bad news and good news.
Bad news: I have not resolved the issue and and am still unable to run PsychoPy in Anaconda on Windows 10.
Good news: A clean install of the new standalone package (2022.1.1) on Windows 10 was successful and I didn’t run into the other issues that had bedeviled me with prior versions.
