Hello,
We have an issue with one of our game on Xbox platform. This is UWP Build and its running fine in windows platform, its starts easily on xbox but crashes soon before level start.

We have tried all possible ways to resolve the issue but its still crashing. Please suggest possible solution to resolve the issue.

Do you have a callstack for the crash?

How do we obtain the callstack after a crash? I have not found the option for that. The crash data Xbox Device Portal
is empty and the legend
Ensure the title VM is terminated in order to see ERA crash dumps. But I do not know what that means

Run the game via the generated Visual Studio project, and then when the crash happens, the debugger will stop and show you the callstack in the callstack window.
