That is usually a corrupt installation. My suggestion:

  1. exit thunderbird
  2. download the same or equivalent version from https://www.thunderbird.net/en-US/thunderbird/all/ (that is, if you are with ESR, stay with ESR. if with monthly, stay with monthly)
  3. although not necessary, I always encourage doing a backup prior to a fresh install.
    • ensure thunderbird is not running
    • enter %appdata% in search window on task bar and press Enter key
    • this should open windows file explorer in Appdata\roaming folder
    • highlight the Thunderbird folder and copy to external media (or a separate folder)
  4. install the downloaded new version
