Tried again and it finally rips!

I've had the same issue and have submitted the dump file 3 times, I think the reason it hasn't been fixed is because they've done the dump file for the US version which now works so when they see the UK version they think it the same

I have the UK UHD Blu-ray of halloween kills & it still shows up as with volume key unknown I've sent my dump twice and it has been almost 2 weeks and still no luck.
