Could be bad. I got Ready Player One new. Looked fine, but had errors in the disc. Had to take it back and get an exchange.
Recommendations for Cleaning New and used 4k Discs.
The first thing to remember is that just because a disc can be played successfully in a standalone disc player, it does NOT mean that it can be ripped. Standalone disc players will skip over problematic areas on a disc while MakeMKV needs all information on the
disc/track to create a lossless MKV file.
If you experience read errors and discs that will not read properly, here are some
recommendations:
1. Gently clean the disc with a soft cloth. Mild non-abrasive soap and water can also be tried.
New discs often have a hazy coating that can prevent ripping, and used discs can have dirt and fingerprints.
I use “Waka Premium Microfiber Cloths”
which I find to be excellent. I bought these on Amazon. Please find the link below:

2. Replace the disc. Just because a disc “looks” perfect doesn’t mean that it is perfect.
Mastering and manufacturing errors do occur and these will prevent successful rips.
Please note that it is not uncommon for you to need to replace a disc more than
once; discs are produced in large batches so if a mastering error is laid down on one disc, it makes sense that it could be there on all discs from that batch.
Also, just one small scratch on a 4K disc can produce read errors and in turn the disc does not backup properly. I have bought discs myself from Amazon which looked perfect but received faulty. When I reordered the next disc then worked., this has happen more
than once.
3. If you get read errors on a disc Increase the setting “read retry count” from setting 5
to 10
4. Try a different or new drive. No two drives are exactly alike so where one may fail to rip, another has no problems. There will always be 4K discs that one drive will read and another will not. This is why customers sometimes will buy for example a Hitachi BU40N or a Pioneer drive such as BDR-S12UHT, BDR-XS07TUHD or
BDR-UD04
