My results have been the same as Alan ^^.
R1, WS, Platinum 126.96.36.199. Beta, PP "always"enabled.
No problems at all.
A few thoughts:
You didn’t mention the region, but try PathPlayer always enabled (not enabled if necessary). If this fails, try disabled.
Try the disc in another ODD.
Clean the disc, even if it looks pristine. Use a microfiber cloth and isopropyl alcohol, windex, etc…nothing that will act as a solvent on plastic.
You can try disabling the read-ahead cache and ignore all read errors, but it’s pretty unlikely that this will work. You also have the potential to copy read errors. This has only worked for me 2-3 times in the past 3 years or more, but you never know
