UHD Neverending Story theatrical US version

[hoppara]

Hi there,

I've just tried to rip the UHD US Theartical of Neverending Story (Imprint master) and makemkv seems to stop reading in the third of the process (stream with chapters) and in the end of the third fourth of the process.

No error message pops up.
Any ideas of what the issue could be?

Thanks a lot

You should try gently cleaning the disc.
