Unable to click-drag objects in Illustrator 30.3 on Windows

Pleaser fix quickly!

This is happening to me as well. Tried all things said and stops working after a few minutes.

Just to eliminate program-wide corruption it might be a good idea to try resetting your Illustrator preferences. Corrupt preferences can lead to erratic behavior. Resetting the preferences will restore the program to its defaults. Hopefully, this process will provide some relief.

To reset preferences on Windows:

You can try the quick way of resetting on a PC which is to hold down Ctrl + Alt + Shift when launching Illustrator and respond affirmatively when asked if you want to reset. There have been some recent reports that the window asking if you want to reset is not popping up but that the prefs are being reset anyway. If this works great but if it doesn’t you may have to manually delete them.

To do so:

On Windows 7 and above the preference files are hidden. To find them go to the Control Panel and open Folder Options and then click the View tab. Then select “Show hidden files and folders” or “Show hidden files, folders or drive options” in Advanced Settings. Then delete (or rename) the folder at the end of this path: C:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Illustrator [version number]\ Settings\<Language>. Make sure that Illustrator is closed when you do this. When you relaunch the program it will create  new preference files and the program will be at its default settings.

The advantage of manually deleting preference files is that after you’ve reset up the program (make sure that no document window is open) to your liking, you can create copies of your personalized “mint” preference files (make sure that you quit the program before copying them—that finalizes your customization) and use them in the future to replace any corrupt versions you may need to delete.

This issue could be caused by a number of different things, including a possible bug in Illustrator. Is the problem happening only in Adobe Illustrator? Are there other applications running at the same time?

For basic troubleshooting measures I'd try rebooting the computer and also checking the connections of the mouse or graphics tablet being used. A bad USB cable or dying battery in a wireless setup can cause issues. If the mouse/tablet is plugged into a USB hub try plugging it into a port on the computer itself.
