Can't wake my mac unless hard shut down

Hi there!

After I've updated my MacBook Pro to High Sierra 10.13.4, I've discovered a very unpleasant behavior: whenever my mac sleeps for more than an hour and I try to wake it up, it stucks after entering the password and not reacting on anything.

However, if I hard shut by holding the power button for couple seconds and then turn it on again, it works.

Nothing is plugged to macbook while - I've tried with and without power cord connected, the situation is the same.
