I use BluetoothLEAdvertisementWatcher.Received() to register scan callback and start scan LE, after scanning, I free the callback and stop scan. It works well, but when exit app, below crash will happend, it seems an inner crash in Windows.Devices.Bluetooth.dll when free something, so what's wrong and How can I avoid it?

Roy Li - MSFT 31,826 Reputation points Microsoft Vendor2024-03-07T07:07:16.31+00:00 Could you please share more information about the real scenario? You mentioned that the crash happens when you exit the app, what actions are you doing before exiting the app? Which line of code throws the error?

2024-03-07T09:59:58.55+00:00 Thank you for your reply，my code is just like below.
I did not do any more things before quit app， I just do start scan/advertiser and stop scan/advertiser before quit app. And my code work well and did not throw any error. The crash callstack is caught by another error detect tools. It shows that Devices.Bluetooth.dll has crashed before exit. Can you find some clue on the callstack ? Thanks.

2024-03-08T07:20:03.65+00:00 I have to say that your issue might more support and it might beyond the scope of the forum.
For your scenario, I suggest that you might need to open a support ticket for this. Please contact our paid support at MS Support. You will get 1:1 support on that. Select Developer Tools -> Windows UWP Development -> Windows 10 Universal App Dev -> Devices and Sensors Development-> Bluetooth API in the support page and you could contact the team. Please kindly note that your support ticket will be free if it is Microsoft's issue.

2024-03-11T03:33:28.5466667+00:00 I have to say that it's hard to define the issue without further investigating. That's why I'm suggesting you open a ticket. If you just want to report such behavior, you could submit feedback in the Feedback Hub. You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. Please select Developer Platform->API Feedback as the category when you submit your feedback.
