Syncfusion.Blazor.Inputs.SfUploader.BuildRenderTree(RenderTreeBuilder __builder)

[Edward A Meijer]

I did a reinstall of Blazor studio and now it will not run.
An unhandled exception occurred while processing the request.
This is a fresh install of VS 2022.
On the dashboard I have option what to install, the only option I select is Blazor.
But in the xml error log it appears it is expecting other items to be installed.

System.NullReferenceException: Object reference not set to an instance of an object.

Same Error.  What the heck.  Are you guy testing these releases?

[Charles Matvchuk]

Rollback to 25.1.35 and the upload manager will start working again.
