A Reprobate Mind Romans 1:28
Does God really turn people over to a Reprobate Mind ? Which means to be (Rejected) Will God's grace give you another chance ? Will God give the saved person who falls and has a hard time returning to the faith another chance even if they have slipped into all depravity ? Does a reprobate mind sound like Hebrews 6:4
Hebrews 6:4-6King (KJV)
4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
5 And have tasted the good word of God, and the powers of the world to come,
6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

Let’s look at the word reprobate for just a moment. A primary meaning of reprobate is “rejected.” Webster’s 1828 dictionary defines it as “not enduring proof or trial; not of standard purity or fineness; disallowed; rejected.” This is also a Bible definition found in the verse you quoted:
Reprobate silver shall men call them, because the LORD hath rejected them.
Jeremiah 6:30
Does God really turn people over to a Reprobate Mind ? Yes! God really turn people over to a Reprobate Mind, When you can see people doing such things as:to do those things which are not convenient, For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
Because that which may be known of God is manifest in them; for God hath shewed it unto them, For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
