Platinum Era :
Some people report playing in windowed mode solved it, others disabled their audio during the battle and some people just didn't look at the core unless they were attacking it when it was exposed.
Nothing helped but i tried the 3rd option and was successful somehow when the core opens i drain half of its life and the when its about to close it makes a sound and crashes.........and it wont close until i look at it....isnt there a way i can order my teammates to destroy the core or destroy it myself in one chance...
Sadly no, you have to destroy it yourself.
Try reinstalling it. Also verify the cache integrity if you are on Steam (Bioware forums fix)

"The common factor seems to be looking into the core while its open. The solutions are to play that room in window mode (seems to always work for me). Or take the CAIN with you, have it up before hacking the door to enter, and charge/shoot the core with the CAIN as soon as you can (ignore the husks).
One cain blast will detonate the core. " (Steam forums)
