Hello, this is my first time using Lutris. I am trying to install ubisoft connect which seems to install but on launch I recieve the error: "Ubisoft Connect has detected an unrecoverable error and must shut down. Crash dump created at “C:/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/crashes”

I have the exact same problem. Tried a different runner as well but same issue. Also tried the “fix” from here (https://www.ubisoft.com/en-us/help/connectivity-and-performance/article/error-message-ubisoft-connect-has-detected-an-unrecoverable-error-and-must-shutdown-on-ubisoft-connect-pc/000064974) but same issue.

It is the same for me and my wife… Both of us are using CachyOS. Worked until a couple a days ago…

I had the same issue on CachyOS today and found the following solution:
- Install ProtonUp-Qt (via CachyOS Package Installer)
- Install GE-Proton10-10 via ProtonUp-Qt (for Lutris!)
- Start Lutris → right click on Ubisoft Connect → Configuration → Starting Options → Wine Version → GE-Proton10-10 → Save
- Start Ubisoft Connect
That worked for me.

You, ma’am or sir are a lifesaver!!! Thank you for your help, it works… 
Yeah this worked for me on Debian 13. Hadn’t started Ubi in ages; well before I upgraded from Deb12. So I thought it was something I had done.
Hi there! I had the same problem, so I followed Unrecht’s instructions, but then I ran into Error Code 256 in Lutris when trying to install an actual game after loggin to my Ubisoft account:
