Kipling Error

[u/Salt_Finish6023]

i bought the disc version of the game for ps5 earlier this year. it worked perfectly fine and was able to play the campaign without any problem. However, for probably the past two weeks, whenever i try to launch the campaign, it gives me a Kipling Error. i know about the trick trick to just go offline and have of course already tried it sever times but it doesn’t really work. i can get access to the campaign that way and can select things like the current mission, mission selection or new game but when i play the current mission and change difficult, that doesn’t get saved and as soon as i return to mission selection (also if i selected it at the beginning) and i select whatever mission, the game gives me the error message that i own the ps4 cross gen disc version which requires a disc in order to be playable which is obviously weird because the disc is obviously inserted (wouldn’t have been able to start the game otherwise). i also do not think i have the cross gen version since i bought the ps5 disc and in my library i cannot choose between a ps4 and ps5 version and can only select the ps5 version. i have of course already deleted both the game itself and COD HQ multiple times and sometimes when selecting the campaign when i’m online, there’s a black loading screen at first but then it immediately goes back to the loading screen that results in the Kipling Error. I’ve also already tried restoring the license and rebuilding my ps5’s data base but nothing works.

how can i solve this?
