[macOS] APP crash when a web custom protocol request is aborted before or during response

[idootop]

Describe the bug

When initiating a register_uri_scheme_protocol request from the web side, if the web aborts the request before or during the response, the macOS APP crashes.

Reproduction

• Register a register_asynchronous_uri_scheme_protocol.
• From the web side, initiate a request using this protocol and abort the request before the response.
• The APP crashes 100% of the time.

Expected behavior

• Before responding, the responder should check if the request has been canceled. If the request has been canceled, do not send the response.
• Or, during the response, catch exceptions to prevent the APP from crashing and quitting abruptly when the request is terminated.

Seems like this is the cause of #1142?

Do you have an idea on how to fix this issue?
