I’m really looking forward to getting back into the game, modder. 👏 I’ve already sent everything as quickly as possible and now I’m just hoping the issue gets resolved soon so I can finally play again. ---

I got the same problem after update it to 0.9.2, last time i play maybe like a month ago, still doing fine, but now when i want to play again, the game doesnt allow me, quiet disappointed especially i already been playing inzoi since day one with more than 100 hours playtime, paid full price. Tried all methods (delete mods, changing connection, restart, VPN, verify game integrity, etc) even reinstall it, still the same. ![Screenshot 2026-06-27 210815](https://europe1.discourse-cdn.com/krafton/original/3X/0/e/0e028249e78567e8f5e4c510103d876793f64305.png) [CRASHES.zip](https://forum.playinzoi.com/uploads/short-url/id7NOoxES5Lpa2N1II5EdEz5rBZ.zip) (887 Bytes) [SteamDiagnostics.log](https://forum.playinzoi.com/uploads/short-url/eVEuakbcXpVsK3IFGp8CmOVMNai.log) (19.3 KB) [DxDiag.txt](https://forum.playinzoi.com/uploads/short-url/9m5EXWyuT42ntCP6CZNnq5DnPoQ.txt) (152.1 KB) ---

Could you check whether the inZOI support team sent you a support ticket email? Make sure to check your inbox (and spam folder, just in case). If you received it, reply to that email and attach the three requested files as well. ---

I’m in the same situation. Let’s give the developers a little more time and see how things go. It’s already been three months, but I’m still hoping they’ll resolve it. ---

There are certain streaming services available which offer inZOI, I think. One would be GeForce Now, but a monthly subscription is needed to use it, if I remember correctly. ---

@HeinziDerHeld Thanks bro ! I think I’ll pass for now. I’ve already spent enough money. I’ll wait until the Steam version of the game is more stable before coming back. I’m worried that if I switch to GeForce NOW and run into more issues, it’ll just leave me even more disappointed and frustrated. ---

Guys! I followed up with the support team by email, and one of their representatives suggested that I do a **complete reinstallation of Steam**. I gave it a try, and it completely fixed the issue! **Important:** You need to **fully uninstall Steam first** —don’t just click “Reinstall.” After uninstalling, go to the official Steam website, download the latest installer, and install Steam again. Once Steam is installed, log in to your account and reinstall **inZOI**. After doing that, the **Steam Authentication Failed** error was completely gone for me. Hopefully this helps anyone who’s still experiencing the same issue. Good luck! 🤍 ---

@Mazikeen I’ve been looking everywhere for a solution to the inZOI issue because I really want to play again. I’ve searched through many places, including Reddit, the Steam Discussions, and even Facebook groups. Quite a few people have mentioned the same problem. Some have even refunded the game and said they’ll buy it again once it’s fixed. As for me, I’ll wait and see what happens after the August update. I still have hope. 🙏 ---

@ryohere Reallly ? . I’ll give it a try tonight (Vietnam time). If it works, I’ll mark this thread as solved. 🤞 Is it necessary to delete the game first before deleting Steam? ---
