i'm a novel freesurfer user and i'm afraid i need some help here, please!

I'm having trouble with the processing of one subject, which exited with Errors. I understand the process fails before completing the recon-all2 part, after topology fixing but then, while correcting surfaces, i don't exactly know what's happening. It seems it can't find the proper output (lh.orig_corrected), is that right?  In that case, how should i proceed or which processing step should i try manually to try to solve this issue?

thank you!!
