@raymond-wh-leung oh right, I will edit it. Trying to fix the build now

Have you tried `-WinUIVersuin 2.6`? There could be a bug with 2.7 version in LottieGen, I will take a look.

Thanks, I will take a look. There are some known issues with the optimizer

@FrayxRulez I was not able to reproduce this bug. What are the command lines arguments that you've used? And what is the version of LottieGen. I think it might be...

I think you should be able to do something like that: ```cs Modified_Player.Source = new LottieLogo1_Modified(); ```

@gscheartA We will release CommunityToolkit.WinUI.Lottie package for WinUI3 soon, as 7.1.3 update. You should be able to use this upcoming package in your app.

Just got the same issue. Need to run Rebuild each time, otherwise getting the exact same error: ``` DEP0700: Registration of the app failed. [0x80080204] error 0xC00CE012: App manifest validation...

@agneszitte have you tried pre-release 8.0.0-rc, does it work for you? There should be full 8.0 release that includes all changes soon.

I was not able to repro this exact bug, but I saw a similar one, that looked very similar to first screenshot. Should be fixed by #551

Fixed in #548
