Hi Raaz,

Based on the shared information and stack trace details, we have checked the issue related to the "Exception occurred in XForms SfCircularGauge control." We created a simple sample using CircularGaugeHeader and applied color to the header using the Sync theme. In our testing, it functioned as expected without any issues. Please find the sample from the attached link

Tested version:

28.1.41

Tested devices:

POCO X5 Pro 5G

Windows machine

Output Screenshots:

Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us with following details,

1. Syncfusion Version

2. Exception reproducing video or Code snippet

3. On which platform(s) (Android, iOS, Windows, etc.) are you experiencing the exception?

It will be helpful for us to check on it and provide you solution at the earliest.

Hi Indumathi,

Thank you for your reply, appreciated.

It is quite difficult to reproduce in sample project as these exception appears in our logs and in firebase, happened to 1 out of 1000 end users as it works as expected most of the time.

It appears on Android.

These exceptions shared above are in the hope that syncfusion team can analyze as its probably related to the merged resources. 

Below is the additional information

On button click on Change theme

If (currentTheme == "Dark")

         App.Current.Resources = new ThemeLight();

In App.xaml

    <Application.Resources>
