//UPDATE 2019-11-19//

The Iron Man 1-3 BluRay + UHD Box I bought arrived sealed. The disks were clean and shiny under every angle. YET THEY WERE DEFECTIVE!

I asked a friend if I could borrow his disks and the WH14NS40 as well as the BW-16D1HT ripped them without an issue!

So the lesson here is that even if the disks is brand new, arrived sealed and looks flawless, it can still be broken!

//END

I got a brand new WH14NS40.
I can rip the Iron Man 1 UHD and the Spider-Man Far from Home UHD just fine with MK "HL-DT-ST-BD-RE_WH16NS60-1.01-NM00100-211711202000" on my

But MakeMKV 1.14.5 encounters a 'FATAL ERROR' while ripping the Iron Man 2 and Iron Man 3 UHD.

Debug log attached.

also tried with the following FW's, always the same fatal error.
DE_LG WH16NS60_1.00.bin
DE_flash_HL-DT-ST_BD-RE_WH14NS40_1.02_NS50.bin
MK HL-DT-ST-BD-RE_WH16NS40-NS50-1.03-NM00600-211711211653

Little update. I could just rip the Spider-Man Far from Home UHD disk without any issue at all. No clue whats going on with those Iron Man 2 and Iron Man 3 UHD disks crashing MakeMKV.
