fed up to play Doom Eternal , too many game crash , for no reason , during playing. Game just exit and i cant finish some achievments cause of that => please Google , fix it
Might also be the developers fault at this point if the game is crashing nonstop for you, which would mean it might be good to let their support now.
Do you have other devices to try if it's maybe only crashing on a specific device? For example if you play with a mobile phone, can you try as well with your TV or a Computer or another mobile phone to see if it's device specific or a general problem?
As Chufu said best thing to do is contact DOOM support instead. I've personally found DOOM eternal to be by far one of the best performing graphically intense games on Stadia and it runs flawlessly for me. Many others have said the same. I think likely you found a weird bug that the Doom team needs to fix.
