Program keeps 'crashing'?

This has just started happening today. I start the program when I open up my laptop in the morning, and leave it open until I switch off my laptop in the evening.

I look up to the taskbar and see that the program is no longer active - so it’s crashing I presume. Or is there a new update that makes it turn off?

Windows 10 is up to date, nothing on the laptop has changed since yesterday when all was fine with eM Client.

Edit: it’s just done it again. I noticed on restarting the spash screen says something about ‘not being closed correctly …’
