I has this problem on Android

I backed down the version CommunityToolkit.Maui 9.0 and the issue is still happening. Pretty sure it has something to do with the update to Visual Studio 2022 17.3.3. This was working earlier in the week.

Has nothing todo with VS. It's probably caused by the the PropertyMapper breaking change added to maui 9.0.5 in the last minute before release. See the release notes for SR5: https://github.com/dotnet/maui/releases

I have this problem both on Android and Windows after I updated MAUI to 9.0.50. The VS version is the same. The only change that started the crashes is updated MAUI.

I downgraded Microsoft.Maui.Controls back to 9.0.40 and the problem went away. My CommunityToolkit.Maui version is at 11.1.0.

[dseinc]

You are correct jarlem. My mobile app works on IOS with this configuration, and popups do show up:

CommunityToolkit.Maui version 9.0.0
Microsoft.Maui.Controls version 9.0.4
Microsoft.Maui.Controls.Compatibility version 9.0.4

Same issue, also on Windows...it happens as soon as you update to MAUI 9.0.5

[marcojak]

Apparently in release 9.0.5 of MAUI they changed the third parameter and now it's not an IEnumerable anymore but a IReadOnlyList.

Had same issue:
Dropping down versions to this solved it :
Microsoft.Maui.Controls version 9.0.4
Microsoft.Maui.Controls.Compatibility version 9.0.4
