Rendering Error: c.setEventDispatcher is not a function

I get this strange error, when trying to open a page of my project. Sometimes I can click it away and the page renders normally, sometimes it shows the wait screen forever.

It's absolutely unclear what triggered this error. The project's code runs just fine, when starting it from Rider IDE.

Any hints ?

Hi @Harald_Schneider,

This is the first time I see this error. We will need to reproduce it somehow in order to tell more. If you have an active subscription you can send us the app to info@radzen.com. Upload it to some cloud storage service and share a download link with us.

Thanks for your reply.
I have no active subscription, still evaluating.
I will try to exclude parts of the code to track it down.

You can check the troubleshooting guide as well: Troubleshooting | Radzen Blazor Studio

The source for this error is a modified blazor.webview.js: MauiBlazorHybridES2019/MauiBlazorHybridES2019/wwwroot/scripts/blazor.webview.es2019.js at main · Eilon/MauiBlazorHybridES2019 · GitHub

This is rquired to make Blazor MAUI Apps run on older macOS, iOS and Android devices.

It usualy works, but throws this error in Radzen Studio.
However, it can be clicked away (you need to click multiple times), and the Studio works as expected, then.

Without this patch, Hybrid Apps are limitd to macOS > 13, Android > 10 oder iOS > 15.
