it seems to me that converting(or attempting to convert) a layer to a smart object makes the error occur

I can confirm that this also happened to me once or twice. However, there were many more occasions which were unrelated to this action where I got the error. Quite often a gradient or adjustment layer caused the issue, sometimes a layer which was dragged into the document from another file was the culprit. For me it usually helped to merge the layer which caused the problem with another layer (could also be an empty one). But sometimes even that wasn't possible because trying to merge layers often resulted in an error notification. 
Since the problem(s) got so bothersome and frequent I didn't see any other soultion than installing an old version of Photoshop.

I always keep a workstation with a older known working version of photoshop. I make a living doing this so i have to always have a backup. I keep one machine with newest upgrade and a second machine with a older known working version.

I tried relaunching, quitting, restarting the macbook, etc and all it doesn't work. The only way is to roll back 1 version earlier.

Same issue - and happened in illustrator. I could save as .jpg and .png but couldn't save them as unified layers. Had to save layers as separate .pngs. Really annoying and hope it gets fixed!
