MacOS-Catalyst-App brings strange error

[TopperDEL]

I created a Uno-app with the latest Uno-template and tried to run it on MacOS Catalyst today. I get an exception on startup stating the "set_Name"-method does not exist on MainPage.

Any idea what that could be?

This is the stacktrace:

This type of error generally means that there's a mixup in UWP and WinUI binaries, though it is supposed to be caught at build time. If you have a way to repro this, we may be able to troubleshoot.

It is a local project. It depends on some Nuget, yes:

Currently I don't get any PointerMoved-event unless I click somewhere.

Ah, Pointer could be this:

(Missing Background on SKXamlCanvas)

Thanks.

If you can extract a repro for the issue, it will be helpful.

It may be that PointerMoved events are not wired in properly. The Catalyst codebase is based on iOS which does have that support enabled unless the screen is touched. @dr1rrb may have some more details and we'll open an issue as needed.

Should/could I temporarily switch to MacOs (not Catalyst) easily to overcome this issue for the moment?
