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

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
