Hi Dan Hunter,
Since multiple Store games started closing immediately after the Windows 11 26H2 update, and reinstalling Solitaire did not help, it would be useful to check whether Windows system components were affected during the update.
Please try these following steps:
- Open Terminal (Admin).
- Run:
DISM /Online /Cleanup-Image /RestoreHealth - When completed, run:
sfc /scannow - Restart Windows and test the games again.
If the games still close immediately, please check Event Viewer > Windows Logs > Application immediately after reproducing the issue and share the error entry associated with the affected game. The Faulting application, Faulting module, and Exception code would be particularly helpful for narrowing down the cause.
I hope this helps identify what is causing the applications to terminate.
