Extremely long load times on INSTALLED game

Since purchasing the Life & Death pack on October 31, 2024, i have had long load times lasting 45+ minutes EVERY load UNLESS i play via cloud. The ONLY long load screen is waiting after signing in, for it to reach the main menu. I have uninstalled and reinstalled the game and all packs several times over the months, i have cleared the cache, i have my console wired DIRECTLY to the router, and I've even bought external memory to put all other games on with only Dims 4 and COD installed on console. Still, 6½ months later, and I'm still having issues. If i play via cloud, i have no load time issues BUT it doesn't come up as a game pass game that i get xbox points for playing like other game pass games though it's on game pass. At this point, i barely play and feel like my money has been wasted because of this.
