Where can I find the LibreOffice error log to diagnose problems?

LibreOffice creates error logs that can provide valuable clues about the cause of crashes or other issues. The location of the log file varies by operating system: Windows: `%APPDATA%\LibreOffice\log`; macOS: `~/Library/Application Support/LibreOffice/log`; Linux: `~/.config/libreoffice/log`. Examine the log file for error messages and stack traces.
