The last few days ive has countless issues with my gta. ERR_GEN_ZLIB_2 has popped up more times than i can count and i cant for the life of me figure it out. i have been modding gta 5 for like 6 years now and i have never had this issue before. I recently reinstalled the game and have been adding back my mods one by one, everything seemed fine. I tested the game between each mod i added. I just installed a addon vehicle pack (this pack in perticular i had in my game the last time i played so i know it works). I edited the dlclist.xml file like i've done hundreds of times before but when i put it back in the game and try to launch i get the error.

I have installed the normal mods for using addon packs, gameconfig, heapadjuster and packfilelimitadjuster. I've also double checked that there arent any errors in the dlc file itself and there are none as far as i can tell. Does anyone know what causes this?

Ok gang, I'm perfect to help cause I just had this same issue it a corrupt game file. I know this is going to sound long and tiredsome but this the best method to find the broken file: install two dlc.rpf at a time and then launch and repeat until you find the file. I find it best to use this https://www.gta5-mods.com/tools/dlclistautocompiler so it doesn't take so much of your time I hope this help if not, let me know if I don't respond. I'm at work then.
