Unable to deploy to iOS local device with "Xamarin.iOS does not support running or debugging the previous built version of your project." error.

I have trouble deploying any MAUI iOS application to any physical local iOS device (iPhone 12 and iPhone 13) via the "Hot Restart" feature of Visual Studio (so no Xcode version is involved). It ends up with the error message "Xamarin.iOS does not support running or debugging the previous built version of your project. Please ensure your solution builds before running or debugging it.".

It can be my work project or the default MAUI template in Visual Studio, the result is the same.

I tried typical suspects - deleting "bin" and "obj" folders (many times), reinstalling MAUI workload via the Visual Studio installer, re-adding Apple developer account and its certificates, reinstalling whole Visual Studio, following the "Can't locate the .NET MAUI workloads" guide at the https://learn.microsoft.com/en-us/dotnet/maui/troubleshooting?view=net-maui-7.0 page and finally in the last desperate attempt reinstalling Windows itself.

Nothing helped, the message is always the same, even though this same setup (project, local device, apple account) works on my other PC.

Any idea, what the problem could be and what else I should try to solve this issue?

Many thanks in advance.

    Ok, I have been finally able to make it work. I am not sure what actually caused my problem and what solved it, but after endless tries, these are the steps, after which, it finally deployed:

      1. I run "dotnet workload install ios" (still didn't work, but it may be important)
    1. Removed "Apple developer account" and added it once again.
    2. In Apple account's "Company Details" I created a new "iOS Development certificate".
    3. In "iOS Settings" I unchecked "Remote Simulator to Windows" (I don't even have Visual Studio connected to Xcode so this should have literally zero effect, but I just describing what I did in my desperation :D)
    4. And in "Android Settings" I unchecked "Preserve application cache on device between deploys". My project is being built for Android, but I would expect that this option would not affect iOS deployment in any way. Similar to the previous point, I don't know if this actually made any difference, but I made all these steps (except for the first one) at the same time.

    After that, it magically started to work.

    Thank you, Wenyan, for your comment, it ultimately lead me to tinker a little bit more with Apple Account, and that probably solved it :)
