There are a few possible reasons why Adobe Illustrator keeps crashing:

• Your Illustrator app is not up to date. Make sure to update Illustrator to the latest version.
• Your computer does not meet the minimum system requirements for Illustrator. Illustrator requires a certain amount of RAM, processing power, and storage space to run properly.
• You are trying to open a file that is too large or complex for Illustrator to handle. Illustrator can only open files up to a certain size and complexity.
• You have a problem with your computer’s hardware or software. A hardware problem, such as a faulty hard drive or graphics card, can cause Illustrator to crash. A software problem, such as a corrupted Illustrator installation or a conflict with another program, can also cause Illustrator to crash.

If you have checked all of the above and Illustrator is still crashing, you can try the following:

• Restart your computer. This can often fix minor software glitches that can cause Illustrator to crash.
• Clear the Illustrator app cache. To do this, go to Edit > Preferences > Advanced and click Clear Cache.
• Reset Illustrator’s preferences. To do this, go to Edit > Preferences > General and click Reset Preferences.
• Reinstall Illustrator. This should be a last resort, but it may fix the problem if Illustrator is corrupted.

If you are still having problems, you can contact Adobe support for assistance.
