A temporary solution, while waiting for the sen2cor developers to provide a version that corrects the problem, is to comment the 2013 and 2014 code lines of L2A_Tables.py from sen2cor 2.9.0 version. This file is located at \Sen2Cor-02.09.00-win64\ Lib\site-packages\sen2cor. I’ve done tests for several Sentinel-2 products and it seems to work fine.
