Hamburger menu freezing on one view only in Release build

Fred Kozlowski 20

I have a view in my AppShell that works totally fine in the Debug build. When I navigate to that view in the Release build using the hamburger menu, the application freezes on the screen that I was on prior to navigation. I can still use the hamburger menu, but I can't change the view.

I have no errors in either Release or Debug. It appears that the screen I'm navigating to is never loading. OnAppearing and OnNavigatedTo aren't running.

All the other views are working as intended.

For further investigation, could you please provide the following information?

The MAUI version.

What is the platform where this issue occurs and what is its API level?

Could you please provide steps that can reproduce this issue or minimize the code sample and update it into the issue?

Your prompt reply will be highly appreciated.

Hello,

Thanks for your feedback.

After testing, this issue is caused by referencing static resources.

<BoxView HeightRequest="1" Color="{StaticResource CustomGrayDE}" Margin="0,0,0,30" />

This issue does not occur if the color or the value of the color, e.g. "Red", is used directly instead of the StaticResource.

Best Regards,

Alec Liu.

You were on the right track, it was another of my StaticResources. Thanks for the solution! It's a shame that this didn't throw an error of any kind.
