Apple Mail Crashes When Searching, But Only for Specific Word

I am trying to search for an email about a flight booked on United Airlines. I can search for the name of the friend who sent me the email, the word "flight," or pretty much any other word, as far as I can tell, but as soon as I start typing the word "United" into the search box, apple mail quits. This has happened multiple, multiple times. I updated my software, and it is still happening. It's the weirdest thing. Any thoughts? I have a Macbook Pro running Sonoma 14.1
