no clue as to what causes it, but when ending the turn in 1544 the game usually crashes/freezes when the 'Counter Reformation' event pops
That's odd. It works fine for me. I tried it twice and the game gives the proper popup and I can select the proper action. Both choices also work fine, no crash or anything, the game keeps on playing past 1544.
Were you doing something else specific in those turns?
