Sen2cor terrain correction stops processing

Hi there!
I’m rather new to sen2cor and I have a little problem when it comes to the terrain correction of my SAFE file.
I used sen2cor via the command line, the tool is installed properly, same with Anaconda. It runs the atmospheric correction perfectly, but when I change the attribute >DEM_Directory> to an empty folder I created in the sen2cor home folder, it starts running the processing until all bands are imported. From here it just stops, it neither cancels the processing nor does it give an error message. I let it run for a few hours already in hope it might continue, but it doesn’t.
At this point I’m cluesless where the problem might be.
Maybe someone can help here?
