Illustrator does't save the file with text on the document

I’ve followed all the steps suggested on the Adobe help page, but it’s frustrating that I can't save the Illustrator file I’ve been working on. It saves fine without the text, but when I include text, it won’t save. I don’t have any corrupted fonts, but I noticed that by default, the text tool selects Myriad Pro. I’ve installed the font on my Intel Mac, and everything seems fine with the font. However, I urgently need to find a way to save the Illustrator document with editable text.
