@KraljStefan96 i wouldn't say it's a conflict, but rather either a poorly written or outdated script that won't run properly or is conflicting with other scripts you installed. That's why i suggested renaming your scripts folder to rule out hardware, software, or integrity issues. Problem could also be asi in root folder but that would be next step.
@puro63 I can't help you because I have no idea how many models you installed and how many mods and which combinations you installed and don't customize clothes. But, I'm guessing you are selecting the wrong torso, wrong legs etc ... and/or you may have installed some components incorrectly.
You need to find the right combination and it can be tricky and frustrating at times.
@Minionek00 If your Menyoo doesn't work you need to have both ScriptHookV.dll and dinput8.dll installed in your game's root folder where GTA5.exe and you need a legal copy of the game, properly updated.
