So i already started isabella recruitment quest but after helping her defeating some bad guys at hightown, we were suppose to go to the chantry but, i don't really know why, i can't seem to enter the chantry. i mean there's no 'clickable' area on the chantry door and now i'm stuck with isabella just standing in front of the chantry door. btw i'm playing the pc version, in case anyone thought i'm playing the console version. 
 
thanks in advance.

Reload a save, happened to me.
 
BioWare is aware of the bug and are working on fixing it.

I don't know if this is some kind of override but for me, I looted the corpse that enters a cutscene during the fight, so the cutscene never happened and Isabella just started fighting toward the chantry and the door opened fine. So maybe try that.

Yes it's a known bug that Bioware will fix in the upcoming patches. It's caused when you looting the corpse before she talks. So just let her talk and then loot the corpses and then you should be able to enter the chantry.

I am sorry, but it has been six years since the last post saying Bioware is aware of glitch and i's fixing it. The glitch has not been fixed. Why would you say that was the case when it obviously wasn't?
