Messages crashes at launch on OS Sequoia 15.5
Messages has been crashing at launch on MacOS Sequoia 15.5. I've rebooted my Mac several times. As soon as I launch Messages it displays the Messages window and then crashes with the perpetually spinning disc. I cannot sign out of Messages or do anything within the app becomes it become completely unresponsive. I'm forced to use Force Quit to exit the app.
How can I fix this issue?
