Can't save as SVG
This is a recent issue I've found with Illustrator 29.3.1 on Mac Sequoia 15.3.1 with M1 chip. I have previously had no problems opening an SVG, doing a slight edit, then saving that SVG (command + S). Now I do that, but when I try to open the SVG again in Illustrator I get the errors "This SVG is Invalid. Validate it before opening.", then "The operation cannot complete because of an unknown error. [STEX]". The SVG seems to be corrupted.
I can't just export as SVG because Illustrator doesn't seem to preserve the opacity settings on my objects when exporting to SVG, and then if I try to update those in Illustrator then I run into the above issue again! I have made sure my Illustrator is up to date - it is frustrating because I have done this before on a previous Illustrator release without issue.
