So, upon further investigation it seems that crush was caused by QTdecoder and DPDdecoder struggling to make sense of an mxf file in a folder I was trying to reach.
What bothers me is that the entire system got compromised and the GPT tables on the HDDs destroyed somehow. How bizarre. Other softwares say “Cannot read file, format not recognized” – Resolve hangs and destroys GPT
I am going to write it off as a beta bug.
