Hey @Captainflask,
sorry I don't speak french, so I am answering you in English and hope this might help you as well.
As far as I understand you are unable to play your games on Stadia on your Samsung Galaxy Tab S, because of an error message that tells you to start the game again.
As far as I can see in this article, that tablet that you have seems to be not supported yet for Stadia. What you can try in that case would be to activate the experimental mode:
- To try playing Stadia on an Android device that is not currently supported, sign into the Stadia app Stadia icon on the device you want to try, open your Stadia settings, tap Experiments, then turn on Play on this device. This setting will only affect the device you set it on, and you can turn it off at any time. Note that your play experience may vary depending on your mobile device and network speed.
I hope this will help to run your games. If that doesn't work, you need to either play Stadia on a supported mobile phone, in the chrome browser or on TV. In that case you can also leave feedback to the Stadia developers that you would love to see Stadia working on your specific device. Just tap your profile in the top right corner in the Stadia app or on stadia.google.com.
I hope the best for you, fingers crossed that it works that way!
