To get more information about this error message, then enable minidumps.

Enable minidumps through Advanced System Settings -> System Properties -> Startup and Recovery -> Settings -> Write debugging information: ‘Small memory dump (…)’.

You will have to reboot the machine, and then you will see fuller logs.

After rebooting, rerun the program to see the crash again and now it will have much more useful details.

Notice: You may also want to build debug so that the dump has more useful information
