Yes, but I didn't know what happened to software. OS is Big Sur 11.5.2 and version of Illustrator is the new one (2021)

Hi there,

Sorry about the trouble you are facing. I would request you to details asked by @michelew83603738.

Also, you may try resetting Illustrator Preferences (https://helpx.adobe.com/illustrator/using/setting-preferences.html) and let us know how it goes.
Disclaimer: Please note that resetting preferences will remove all the custom settings, and Illustrator will launch with default settings. You can also take a backup of the folders in case you want to. Location is mentioned in the article.

Thanks & Regards,

Anshul Saini

Hi,

I already resetting Illustrator Preferences. But it is still fail.

OS is Big Sur 11.5.2 and version of Illustrator is the new one (2021)

Thank you for sharing the details. I would suggest you try the following steps and let us know how it goes:

• Rename the CEP folder to CEP.old from the following location:
  

  /Library/Application Support/Adobe

• If that doesn't help, rename the extensions folder to extensions.old in the following location:
  /Library/Application Support/Adobe/UXP
• If that doesn't help either, uninstall the application using the CC Cleaner tool and reinstall from the Creative Cloud Desktop app.

Regards,
