What is the clarification of the verses that do not mention the acceptance of repentance or forgiveness for some sins, such as polytheism, or those who exchange God's covenant for a small price, and do these verses indicate that their repentance will not be accepted in this world?

The verses that speak of torment in general, and specifically with definitive proofs of the acceptance of repentance, such as His (the Almighty) saying: "Say to those who have disbelieved, if they cease, what has passed will be forgiven for them," and His saying: "Say, "O My servants who have transgressed against themselves [by committing sins], do not despair of the mercy of Allah . Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful."

Moreover, Allah replaces the evil deeds of those who committed major sins, such as polytheism, with good deeds, if they repent, believe, and do righteous deeds, as in His (the Almighty) saying: "Except for those who repent, believe and do righteous work - for them Allah will change their evil deeds into good ones. And ever is Allah Forgiving and Merciful."
