Thanks for filing an issue! Please answer the questions below so I can help you. * iTerm2 version: 3.4.1 * OS version: 10.15.4 * Attach ~/Library/Preferences/com.googlecode.iterm2.plist here: [com.googlecode.iterm2.plist](/uploads/6a320268651c92bd5d779f744a1298f8/com.googlecode.iterm2.plist) * Attach a debug log, if possible: [debuglog.txt](/uploads/02ccb198ae8d8b07891462afd0d5072b/debuglog.txt) Detailed steps to reproduce the problem: 1. ??? 2. Open a terminal tab or split pane or window What happened: "Session ended (broken pipe). Restart it?" What should have happened: A new tab/window This is new since I updated from version 3.3. I found #9113, but I have no running iTermServer processes (or any processes whose name contains iTerm but is not exactly iTerm).
