Hi @kaike,
Thanks for sharing the details. Could you please confirm which version of macOS you're using on your M4 Pro MacBook? I'd recommend manually resetting Illustrator preferences and testing again. Ref: https://adobe.ly/4oirj7M. If the app still crashes on launch, please try starting your Mac in Safe Mode and then launch Illustrator to check if any third-party plugin or extension might be causing a conflict: https://adobe.ly/4331no0.
If it continues to crash, please follow the troubleshooting steps mentioned here: https://adobe.ly/3LxPAIe.
I also checked for any crash reports submitted using your community email but couldn't find any. Please submit a new crash report and share your email address with me via DM, so I can locate the logs and review them. You can find the steps here: https://adobe.ly/4oeb8Iq.
Lastly, the latest version of Illustrator is 30.0, so please try updating to it and see if the issue persists.
Looking forward to your update.
Abhishek
