Hi there,
Apologies for the delayed response. I hope your issue is resolved by now.
If not, please make sure you have OS & Illustrator updated to the latest version. You may also try resetting the preferences of the app manually:
- Close all Adobe applications.
- Go to Location C:\Users\user\AppData\Roaming\Adobe
- Rename Adobe Illustrator and Adobe Illustrator 24 Settings folders to Adobe Illustrator.old and Adobe Illustrator 24 Settings.old
- Launch Illustrator from the Creative Cloud.
**Please note that resetting preferences will remove all the custom settings and Illustrator will launch with default settings. This way all your old settings will be saved in .old folders and Illustrator will recreate new folders with default settings.
Hope it helps.
Regards,
Ashutosh
