Illustrator 2023 crashing | Sorry, illustrator has encountered an error and needs to close error 205

i'm having the same issue, crashed numerous times, so i started over with a new file, tried to draw some simple lines and the file is completely locked. I will look at the linked article.

I have been having this same problem.  I have done everything on the support page as well as uninstalled and reinstalled Illustrator 2023 multiple times as well as deleted the preferences.  None of this has stopped the error 205 messege I get when I start the program.  This is getting extremely frustrating, especially since this is a subscription based program now.  Does anyone have any fixes that I havent already tried?

I've got the same issue after updating last night. Just hopeless! I'm guessing it hasn't been tested properly before release... 

If when you updated the program you used the option to import previous settings and preferences then that could be the issue. Try deleting your Illustrator preferences and see if this process—which returns the program to its defaults—helps solve the problem.

To do so:

For Macintosh Users: The User Library folder in which Illustrator’s preferences are stored is hidden by default on most Macintoshes. To access it make sure that Illustrator is closed and click on the desktop to launch a Finder Window (Command-N).With this window in column view follow the path User>Home folder (it’s the folder with an icon that looks like a house—it may have the user’s name rather than “Home”) and click on the Home folder. With the Option Key pressed choose Library from the Finder Go Menu. “Library” will now appear within the Home folder. Within the Library folder find the folder called Preferences and within it find the folder called “Adobe Illustrator <Version #> Settings” (earlier versions of Illustrator might just say “Adobe Illustrator”) and the file called “com.adobe.Illustrator.plist” and delete both that folder and that file. When Illustrator is next launched it will create new preference files and the program will be restored to its defaults.

For Windows Users: 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.
