How do I fix an unknown error has occurred in Illustrator?

1. Unclutter the file

We are talking about Illustrator, a memory-depleting application, which means that the unessential elements present in your document can increase the size, which in turn will lead to file corruption.

So, we advise you to try to delete all the trash that is present in your current projects, such as the duplicated elements, sketches, and many others.

Doing so will significantly reduce the size of your file, making it less likely to be prone to errors when saving it to your device.

2. Save the file using a new name

Another easy solution for fixing your saving issue in Illustrator is to actually save the document with a fresh new name which will generate the same file with non-corrupted patterns, gradients, and fonts.

Why? Because using this process is the same as rebooting your system, which you can try since we’ve brought it into the discussion.

Remember how we keep saying that the simplest solutions work for what appear to be the most complicated problems?

You can also try transferring the file in question to a new document, which is yet another proven solution for this issue.

Initially, you have to copy all the elements that you have inserted or used in your project, then paste them into a fresh new document.

Now, all you have to do is simply save the document and check if you can open and edit it again. That’s pretty much it.

How do I reset Illustrator preferences?
