The problem originally reported for WPE: https://github.com/WebPlatformForEmbedded/WPEWebKit/issues/1220: Steps to reproduce: 1. Run WPE-WebKit-based browser with remote web inspector (RWI) enabled 2. Navigate to URL: https://scony.github.io/stb-lab/console-spam/index.html 3. Connect to RWI and make sure console logs are spamming to console 4. Close RWI connection (I'm basically closing the tab of the chrome browser where I connect to RWI from) 5. If no WPEWebKit-based browser crash is seen, go to step 3) The crash can be also reproduced on latest main with remote web inspector(http/inspector) run from chrome/epiphany/webkitgtk

It seems that after closing remote web inspector connection it is possible that some of messages can be still sent from WebProcess to UIProcess and in RemoteInspectorServer::sendMessageToFrontend there can be a crash because of missing socketConnection which was removed by previous closing remote web inspector connection(RemoteInspectorServer::close)
