Why LR Classic CC always flash back?

[Davidhb-8VYSXy]

I already purchased the Photography Plan as monthly subscription which included LR CC/LR Classic CC/PS, both LR CC and PS work well, but every time I start LR Classic CC, It always flash back, my computer is MacBook Pro, does anyone know what is going on and how to fix it? Thanks a lot!

Give us some more information of what is happening. Add screenshots maybe as well?
