There’s a thread in the bug section: iniBuilds A320neo v2 freezes
Maybe you can describe your issues there and it gets recognized by the devs.
In the meantime I had the 5th freeze in the 5th flight from EDDW to LKPR (Bremen - Prague). It happened every time in the approach phase, a few miles prior landing at LKPR. Maybe it has also something to do with the scenery around LKPR.
