The important parts are

and

IMO, this seems like a Syncfusion issue. I would direct this to them first, as I think that's the issue's root. If it is MAUI, they can circle back.

@PureWeen @mattleibow what do you all think?

I get the same exception when using Carousel in MAUI, it started in version 8.0.60, I tested it in v8.0.40 and it works fine there. I even tried it in the latest nightly build, 8.0.70-ci.net8.24139.2 and it happens there as well. For me it takes place when I move to the 4th page of the carousel, the first 3 pages work fine, as soon as I try to move to the 4th page I get the crash.

@PureWeen @mattleibow what do you all think?

Yea, the error here is that a view is being removed from a layout that is no longer connected.

We do get the index as part of the remove command

image

so, in theory we could use the index vs the platform view to remove the view, but I do worry this just moves the exception down the pipeline. Because there shouldn't really be a path like this triggering.
