for those that use Apple?
Hello @andreac75249358,
Sorry to hear about this experience. Kindly try these steps for macOS and check if it helps:
- Close all Adobe applications.
- Go to the following locations:
~/Library/Caches
~/Library/Application Support/Adobe
~/Library/Preferences
- Rename Adobe Illustrator, com.adobe.illustrator and Adobe Illustrator 26 Settings folders to Adobe Illustrator.old, com.adobe.illustrator.old and Adobe Illustrator 26 Settings.old
Launch Illustrator from the Creative Cloud.
Note: Location starting with this "~" sign indicates the User Library, which is hidden. So, you need to copy & paste the exact path in spotlight search or from Finder Menu > Go > Go to Folder > Paste the location in the dialog box like this:

Disclaimer: Please note that renaming preferences folders 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. The location is mentioned above.
Also, try rebooting your computer in Safe Mode (https://support.apple.com/guide/mac-help/start-up-your-mac-in-safe-mode-mh21245/mac) and share your observations.
Looking forward to your response.
Thanks,
Anubhav
