Whitelisting the whole game folder is not a good idea. It makes you vulnerable for targeted attacks (hacker could look for potentially whitelisted folders on your machine to execute malicious code from within). Usually it’s the developer who should submit their false positive to the microsoft for analisys I believe so they can be automatically whitelisted in their database (don’t quote me on that though).
Providing refunds on Strike Eagle while keeping it in store is a bit strange. It’s like they don’t know if they are able to support it or not in the future.
edit: I think this is a link where you can submit your files:
