I have Visual Studio 2019 (8.10.10.8) with Xamarin Mac (7.14.0.27) and Xamarin iOS (15.0.0.6). I am not seeing any updates to any of those in check for updates, so I am pretty sure they are the latest.
When I debug my app on an iPhone 8 or iPhone 13 (or any iPhone that I have tried), most of the time after not very long the app will stop responding and seems to be locked up.
If I then kill the app, Visual Studio still thinks it is debugging, though it doesn't really do anything.
If I unplug the iPhone then Visual Studio comes back alive.
This has been happening ever since I have been using Visual Studio 2019 for the last year or so on this project.
I do not get any crash reports or exceptions that I can detect.
How do I determine what is causing it to lock up?

Trust This Computeron your device, please refer to https://learn.microsoft.com/en-us/xamarin/ios/deploy-test/wireless-deployment?tabs=macosIn addition, you could check the
Apple Developer AccountsofPreferencein VS. If the issue still exist, I think it is caused by the performance of mac and the buiding caches. You could try to clean bin/obj folder of your project, then try to clean Xcode caches, go to~/Library/Developer/XCPGDevices/remove the data.~/Library/Developer/Xcode/DerivedDatathis floder is the data of simulator, you could also delete.If you still can't debug the app by iOS device, you coud report it to Visual Studio for Mac. Please refer to https://learn.microsoft.com/en-us/visualstudio/mac/report-a-problem?view=vsmac-2019

2021-10-13T13:58:55+00:00 I am not sure you understood my issue.
I AM able to deploy the app over USB connection just fine.
It is that the app will be in the middle of running and I can debug and then randomly the app will lock up.
This is not a deployment issue. It is a debug stability issue.

2021-10-14T05:11:04.53+00:00 Sorry for my expression, I know you can deploy it to your device, I mean debug the app in real device. If the above suggestions don't work, I'm afraid you coud report it to Visual Studio for Mac.

2021-10-14T13:36:01.307+00:00 Yea, none of that helps. It still works fine for a while and then stops responding.
I have reported this to the Visual Studio for Mac team with no response.
Hopefully the new version will work better. I hear it is supposed to be a big change, so I will cross my fingers.
i was just hoping someone here might know of something.
