Sharia law does require the execution of apostates. As muhammed said:
“Anyone who changes his (islamic) religion, kill him”
ex Muslims won’t be punished if not involved in conspiracy against Muslims/ involved in ethnic cleansing of Muslims etc.

Is Apostasy a Capital Crime in Islam?
By Dr. Jamal A. Badawi**
…Behold, as for those who come to believe,
and then deny the truth,
and again come to believe,
and
again deny the truth,
and thereafter grow stubborn in their denial of truth —
God will not forgive them, nor will guide them in any way.
(An-Nisaa’ 4:137)
It is important to note in the above verse that if the Qur’an prescribes capital punishment for apostasy, then the apostate should be killed after the first instance of apostasy.
As such there would be no opportunity to “again come to believe and again deny the truth, and thereafter grow stubborn in their denial of truth”.
In spite of these acts of repeated apostasy, no capital punishment is prescribed for them

Islam & Freedom of Belief
–Ahmad Kutty
…Even though the penalty for treason was the death penalty (as was the case in the Law of Moses as well), there was **no targeting of people who simply chose to leave Islam without any implication of treason. **
To simply kill anyone who chooses to follow a religion other than Islam is against the fundamental teachings of the Qur’an.
Freedom of conscience is a fundamental principle of the Qur’an that is clearly stated in many Qur’anic verses. I list just a few:
Had your Lord willed, all the people on earth would have believed.
So can you (Prophet) compel people to believe?
(Yunus 10: 99).
Say,
‘Now the truth has come from your Lord:
Let those who wish to believe in it do so, and let those who wish to reject it do so’
(Al-Kahf 17: 29).
[So (people) respond to your Lord before there comes a Day that cannot, against God’s will,
be averted—you will have no refuge on that Day, and no possibility of denying (your sins).
If they still turn away (remember that) We have not sent you (Prophet) to be their keeper: your duty is to deliver the message]
(Ash-Shura 42: 47-48).
There is no compulsion in religion:
true guidance has become distinct from error,
so whoever rejects false gods and believes in Allah has grasped the firmest hand-hold,
one that will never break.
Allah is all hearing and all knowing
(Al-Baqrah 2: 256).
Allah Almighty knows best.
