Errors

Hello @Bappy Mozumde24954240j800,

Sorry to hear about this experience. I would request you try resetting Illustrator's preferences as suggested by Eric by following the steps shared in this article (https://helpx.adobe.com/illustrator/kb/troubleshoot-preference-issues.html) and sharing your observations.
Disclaimer: Please note that resetting preferences will remove all custom settings, and Illustrator will launch with the defaults. You may take a backup of these settings from the location mentioned in the article. 

If the issue persists, kindly try running Illustrator under a different administrator account and check if it helps.

Looking forward to your response.

Thanks,

Anubhav
