Puppet warp tool greyed out in Illustrator 2020 on Windows 10

Hi there,

Sorry to hear about the trouble you are facing. I would request you to share a few more details along with the ones asked by @Mylenium:

• The exact version of Illustrator
• Have you selected any layer or object?
• Is the issue related to a specific document? If yes, could you please share the document with us? You can upload it to the Creative Cloud (https://helpx.adobe.com/in/creative-cloud/help/share.html) and share the download link.
• When did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates, or web extensions installed recently.
  Does resetting Illustrator Preferences ( https://helpx.adobe.com/illustrator/using/setting-preferences.html) help to resolve the issue?
  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.
• Does updating Illustrator to the latest version help resolve the issue?

We are here to help. We just need more information.

Thanks & Regards,

Without any info about your artwork and how you used the tool nobody can tell you much. A screenshot of the situation certainly would help. Most likely you created a construct that prevents further editing by adding something or rearranging layers. Otherwise of course I could imagine the eternal hardware acceleration problems getting in the way, so try toggling the drawing modes from GPU accelerated to software-only and back.
