Cubase - Vienna Ensemble Pro 7 - Correct Project close procedure

Hi People!
I was wondering if anyone has been able to find instructions on exactly the correct way to close down linked projects when using Cubase 12 and Ensemble Pro 7, where Ensemble Pro 7 is on a slave computer.
Every time I start Cubase after having closed a project down (on the latest Cubase update, I have the grey dialogue box which gives me the option to send log files to Steinberg, disable 3rd party plugins etc.
Upon closing, there’s no apparent error, but Cubase thinks there was a problem, obviously, because it shows that screen at startup next time.
I feel like I could be doing something wrong, but I just can’t find anywhere at all, some instructions from Steinberg, VSL, or an experienced user on how best to close a linked project.
