Hi Arthur,
Based on the shared screenshot and details, you are using numeric textbox in your sample. In the screenshot, we see that the error occurs due to the two missing packages namely Syncfusion.ExcelExeport and Syncfusion.PdfExport. These package are not required for numeric textbox component. The mentioned issue can be resolved by removing the package in your end. Also, Could you please provide the details whether you are using these package in your end? If yes, please share the component details used in your application. This will help us to provide further solution.
Also, we would also like to inform you that the Syncfusion Blazor UI components from version 18.4.30 are available separately in individual NuGet packages. Please find the link below for more information.
Regards,
Vignesh Srinivasan.
