Start with var/search/__init__.py at SetBrowser.set_browser and var/search/selenium_search.py at get_urls and parse_search_results. Reproduce the reported ./zeus.py command on the stated Linux aarch64 environment, then determine the expected handling for the geckodriver Exec format error and verify the scanner no longer produces an unhandled exception.
