For further investigation, there are several questions to determine.

What's the detailed VS version?

What's the Xcode version?

Does this error still exist when you create an empty Xamarin.Forms project and pair to Mac again?

The error occurs on Android platform, are there any other prompts on Android platform?

Visual Studio 2022 v17.5.1 ,x_code v14.3.

Due to the X between Visual Studio 2019 and Mac_ Code pairing keeps prompting, so the file cannot be created again when it already exists, so Visual Studio 2022 was used

What's the "X" meaning? Is it AndroidX library? Do you have other Android error prompts?

This error usually means you have many versions of VS in your Windows machine, and they all want to pair to mac. You can forget the connection, and clean the Broker, IDB, Build, and Designer Agents on the Mac. (Delete the XMA folder in Mac and Windows machine)
Pay attention to re-opening VS and re-pairing to Mac.

In this thread, we are mainly discussing about this simulator not found issue as indicated by the first post. And you can try to download the builds into your Mac.
But it looks like you want to keep using Xcode14.2 and VS 2019 and you meet the connection issue. For this, it's recommended that you report a problem with the Visual Studio. (And create a new thread at DC)
I updated the answer. Please feel free to post in here if you have any other issues.

You mean you don't sure if the issue will disappear when you go back to Xcode14.2 and keep using VS2019, right?
