Sen2Cor 2.4.0 stalls on Scene Classification

Hi all!

I have been using Sen2Cor for a couple of months now, and has been a really nice, open source code to use in my atmospheric correction.

However I have come across an issue in the latest Sen2Cor 2.4.0 correction of older imagery with a naming convention such as:


This processing that appears is as follows:

and it just stalls at this, and has been like this for 24 hours.
I have tried it on images with the newer naming convention e.g.:


and it works - so it may be an issue with the earlier imagery.
However, this older imagery worked with Sen2Cor 2.3.0

I have been using both the standalone and Anaconda software.

Any help you can give would be greatly appreciated,

Best wishes,
