H @Celia Taylor ,

Welcome to the Community! Can you try to log out of all Atlassian accounts and re-log in using an Incognito window? Then try the app again.
If that doesn't work, I'd recommend to reinstall Trello app. 
You can also try: to fully quit the Trello Desktop App; clear the Trello desktop app data(delete the Trello folder); re-logging via browser; and then open the desktop app again.
