I can't find information about this error for VS2022.

May I ask can you debug on Windows platform? Are you building on a real device or an Android Simulator? If you build and run the app on the Android simulator, try to open Task Manager on your PC, end the Android Emulator task and the VS task, then re-open VS, try to build again. It may be caused by the Android Emulator, you could report this problem about Visual Studio 2022, see https://learn.microsoft.com/en-us/visualstudio/ide/how-to-report-a-problem-with-visual-studio?view=vs-2022
I can debug on Windows platform. I can't debug on a real device and Android simulator. When I created a new project, it works. Only my project have problem with debugging
Since this issue is only on your current project, you might need to open a support case, please contact our paid phone support at MS Support. You will get 1:1 support on that.
Glad you solved this issue, I converted your comment to an answer, so that someone with the same issue can refer to it.
I solved problem. In properties, the project was set debugger as c++. I set as .NET (Xamarin) and the project works.
