Hi all,

I've just done a fresh install on my new M5 Max Mac Studio and all has gone well with the exception of MakeMKV. I'm running V2.0.0 and have a registered version (not beta). When I try to open an .iso I'm receiving the error "Fatal error occurred, program will now exit". This happens whether I try to open the file directly or mount it first. I've tried multiple .iso's and I've also tried opening a 4k blu ray which opened no problem.

Can anyone give me any suggestions as to what the problem might be?
