Thanks :) @fireborn so I looked into this, but turns out the issue wasn’t with the msix.TLDR, I switched ui frameworks and now it’s working. Insane, but a bunch of known issues with Maui projects cause failure to run if installed with MSIX. I’m using qt now because MS doesn’t know how to make a native ui framework that can be packaged, installed and run via a package they made, on an os they made. Guess this why win apps are PWA and accessibility going to hell in a hand basket.
