Thank you @aracelil for your suggestions. In the end, it turned out that the theme, for which no update notifications appeared either on the WP dashboard or in Appearance > Themes, actually needed to be updated. Once the theme and its core plugin were updated, the Elementor update was successful and the site did not crash. Thank you again, Veronica
Thank you @quantumcloud for your investigation and your explanation!
