Microsoft did something to correct problems with the new Windows 10 fairly recently. Also the Microsoft Solitaire Collection app updated. I no longer having problems with Windows 10 or the games.
I never saw an acknowledgment of the fix but something happened. The 121003 pops up when Microsoft cannot attach to the cloud data for the Xbox games. There is an option now to use the cloud data which will allow you to play and Xbox will save your data.
Many of us have tried and failed to find technical help from Microsoft and Xbox for the error code. Basically there is no help for the code. It's just an announcement that Microsoft cannot reach cloud data. The only thing I've found that works is bypassing
the cloud data.
I have auto-install for updates too. I knew going back to the older version of Windows 10 would not be a permanent solution.
Hopefully, this works for your devices.
