Description Of Issue

Up until yesterday ROON has worked flawlessly for me. My Core is running on a Mid 2011 iMac with High Sierra v. 10.13.6. I closed out of the Roon application and when I tried to reopen it, it begins to open, gives me the screen with the quote, then shuts down. Ive seen others have this problem but none have a good explanation or solution. All of them say it just randomly started working again. Please provide any assistance you might have.
