Hi Liam H.1,
Thanks for using Microsoft products and posting in the community.
I realize that you've encountered a problem with launching the game automatically deleting the game and I understand how you feel.
Usually, starting the game will not automatically delete the game, you can try the following methods to check whether it is caused by third-party software interference:
1.Turn off third-party antivirus.
Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed.
2.Disable all third-party programs, i.e., a Clean Boot: How to perform a clean boot in Windows - Microsoft Support
Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.
Feel free to post back if you need further assistance.
Best Regards,
