Hi there,

Sorry about the trouble. In addition to the question asked by @Doug A Roberts, I would request you to share a few more details like:

• OS and version of Illustrator
• 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.
• Did you try re-installing the app? If not, try the CC Cleaner tool to uninstall the app and reinstall it from the Creative Cloud Desktop app.

Thanks & Regards,

Anshul Saini

I have trhe same issue.

It happened once 2 weeks ago, and today it happened again

Windows, Ill 26.1

No changes to my system that I know of.

I have not tried re-installing the app

Same file by any chance?

I hate to say this, but two weeks between corruptions isn't bad! Of course it shouldn't happen, but that it happens this infrequently is a blessing - I swap out my saved pref file once a week on average.

i re install illustrator and that was solved

You shouldn't need to reinstall, just save a copy of your prefs file after you've made all your preferered changes, then if (when) this happend again, replace with your back-up...
