Expected Behavior

Sending messages via the ipcRenderer's sendSync/invoke methods should work consistently, and not throw unexpected errors.

Actual Behavior

When using sendSync/invoke a certain amount of times an error is thrown which crashes the app: "TypeError: e.sendReply is not a function" when calling ipcRenderer.sendSync/invoke

Testcase Gist URL

No response

Additional Information

This bug can be easily reproduced in versions 12 - 22, by setting an interval in the preload script, which calls sendSync/invoke, and listening and returning a value in the main module.

in preload: setInterval(async() => { ipcRenderer.sendSync('TRIGGER_SEND_REPLY'); ipcRenderer.invoke('TRIGGER_HANDLE'); }, 10);

in main: ipcMain.on('TRIGGER_SEND_REPLY', (ev) => { try { ev.returnValue = ''; } catch(err) { console.log('error occured on TRIGGER_SEND_REPLY') } });

ipcMain.handle('TRIGGER_HANDLE', () => { return ''; })

This issue still exists in version 22.3.24, but there is no stable way to reproduce it. It seems that this problem will occur whenever a specific webpage is loaded.
