Transform controls disappeared 2020 Update

Basically, it is not normal what you are describing and it should not work this way.

Normally, I don't like to recommend to reinstall the entire application, but you may try it and see if it helps. Sorry, I have no other ideas that may solve the issue.

Hi there,

Sorry to hear about this. This is really unusual behavior. I'd request resetting the preferences manually following the instructions below and see if they help:

• 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.

You may also try disabling the GPU Performance under Preferences > performance to see if it helps. Let us know how it goes.

Regards,

Ashutosh

What happens if you quit all active applications and then restart your computer?

Can you post a screenshot that shows an object that is selected with the Selection tool (black arrow)?

Can you try if resetting the preferences helps?

Rename the folder as described in here: https://helpx.adobe.com/illustrator/using/setting-preferences.html
