Hi,
Since 24.2.x SfToast can throw this error in some cases : Cannot read properties of null (reading 'removeChild').
It can occurs when we navigate on a page with an SfToast element and move on another page.
Here you can test (by clicking twice on the toggle button) that it was working on 24.1.4x and fails on 24.2.x : https://blazorplayground.syncfusion.com/BXVftrtVotLvwoXx
It can be solved if the <SfToast> element is moved inside its target, but it's still a regression comparing previous versions.
Regards,
Julien
