Hot reload crashes with `System.ArgumentException: An item with the same key has already been added.`

### Describe the bug
I'm running my Aspire-based project with `dotnet watch`, edit a file, and suddenly I'm not running the project anymore.

The project consists of an Aspire host, and the main application using Razor Pages. Crash happens no matter if I'm editing `.cshtml` or `.cs` files, seemingly. Could be connected to #48795?

Also, Aspire dashboard loses connection way before I see the actual crash in the console.

### To Reproduce
I'm not sure if I can provide a repro, since it seems to happen randomly.
