By the way, the bug to look at 'About Plugins' which closes PSE is still there.
I thought this bug affected only the Expert editing mode in PSE 2018. When I was checking the other two modes -- Quick and Guided, I found out these two will also crash and PSE 2018 will shut down. I guess I had not noticed it before because I pretty much use the Expert mode only.
