MacOS 26.3 Messages app crashes every time on launch. It started doing this on MacOS 26.1 or 26.2. I still get message notifications in the upper right corner. But, if I click on the notification banner or launch Messages from the Dock, nothing shows up and the crash reporter window pops up. I've submitted many crash reports to Apple. It's very frustrating because I frequently use Message on my Mac and now it is not working.
I deleted the iChat plist file from ~/Library/Preferences and restarted my Mac several times. Messages still crashes.
I deleted ALL the iChat and Messages plist files from ~/Library/Preferences and restarted my Mac several times. Messages still crashes.
I reinstalled Tahoe 26.3. Messages still crashed. Deleted both plist files and rebooted. Messages still crashes every time.
