我认为这是#15211的复制品

That issue has been closed, but it cannot be resolved

@justlucky are you using any themes?

Yes, using the default theme, this issue only exists in the .net8 environment and not in the .net7 environment.

@justlucky are you using any themes?

I think OrchardCore failed to adapt to the underlying mechanism of .net8, and it is normal for .net8 template projects to output blazer server components.
