I never got the mod to work for 2K21 either. I tried again with 2K22. The gooeyglobal.iff file caused graphics issues. The stadium files (Sxxx.iff) also caused issues but may work with the shared folder by TGSoGood added. I removed these from my Mods folder. These issues may only effect 2K22 only. After this I had crashes but only at the end of quarters. I removed the sound effects files, sfx_inside*.iff. All 8 files and I've played 4 games without a crash. Knock on wood. Maybe this will work for some of you for either version.
Nevermind. Just got a crash coming back from halftime.
