Halo Wars 2 - New Win 10 PC issues

I have been playing Halo Wars 2 almost every day for 1.5 years. Damn thing worked fine until this morning. I got an error that it was not working in my account or something. Damn MS support people wasted 2 hours of my day doing an MS Store reset, MS updates, etc. They then told me I needed to update from Win 10 build 1803 to the latest 1903 build - skipping the much hated 1809 build. I did this. Still no luck. I uninstalled the game, did another “wsreset” rebooted and tried again. Now Halo Wars 2 tells me it is not available to run on my damn computer. Only thing that actually changed was my Win 10 build. Anyone else see this crap, and how are they going to fix it?
Thanks!

theres no fix yet, multiple people having this issue
