I suspect this is because of this Apple bug that I have mentioned before:

https://lists.macports.org/pipermail/macports-dev/2020-November/042641.html

Please check if Xcode 12.3 still has the problem. If it does, please file additional bug reports with Apple about this and mention that it is a duplicate of FB8915358 so that they realize how many people it affects so that they fix it.
