I'm having the same problem with my LG 65" OLED C6. It seems that some shows are playing fine but I get the 5.2.12 error when playing 4K HDR content. I've restarted the tv, reinstalled the app and even changed password hoping to refresh any mismatched session data. The show plays for a few minutes then just stops with the error.
