InDesign is shutting down. A Serious Error was detected
Hi,
Since I updated to Indesign CC 2018, I've had problems with Indesign unexpectedly quitting as well as anytime I move something, anything on a page or try to move to the next page in a document, I get the spinning wheel for about 15/30 seconds which is slowing down my workflow.
I also have had a message on 3 occasions to say Indesign is shutting down due to a serious error (please see attached screen grab).
Any help would be appreciated.
Thanks.
