Did you try this solution? (You probably did?)

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Compiling error after upgrading to MacOS Big Sur

Spot on diagnosis! Thank you! Doing the following as it’s suggested in the link you sent: sudo rm -rf /Library/Developer/CommandLineTools xcode-select --install then a clean installation of Anaconda and PyStan solved the issue. Thank you so much!
