I can add that 0.00 score may be correct for another move (58.Bd1) when the
white bishop can prevent the king from going to d5

I guess that shredder can find 58.Bd1 at longer time control.

Shredder seems to have some knowledge that caused it to get wrong evaluation for
the endgame.

It believed at moves 40-54 that white is better because white has all the pawns
in black squares when the bishops are in white squares.
