Yes, I still use the MinidumpDiagnostics.exe all the time. They just happened to finally remove it out of the engine completely in 4.25 or whenever it was. However you can still go back to older versions of the Unreal Engine to get the tool yourself, but it only works on UE4. Otherwise you will have to update the source code for UE5.
Perhaps I’ll provide my own version in the future, with support for a new web receiver project, since the engine developers cannot take the time to support any of this.
