CCC 1054 Those who die in God’s grace and friendship imperfectly purified, although they are assured of their eternal salvation, undergo a purification after death, so as to achieve the holiness necessary to enter the joy of God.
But remember that purification of Purgatory takes place out of earthly time.
Suffering of humanity with a Heavenly destiny is over at the end of time.
Then-Cardinal Ratzinger cited by MarcoPolo
here:
The transforming ‘moment’ of this encounter [Purgatory] cannot be quantified by the measurements of earthly time. It is, indeed, not eternal but a transition, and yet trying to qualify it as of ‘short’ or ‘long’ duration on the basis of temporal measurements derived from physics would be naive and unproductive. The ‘temporal measure’ of this encounter lies in the unsoundable depths of existence, in a passing-over where we are burned ere we are transformed. To measure such Existenzzeit, such an ‘existential time,’ in terms of the time of this world would be to ignore the specificity of the human spirit in its simultaneous relationship with, and differentiation from, the world. (Ratzinger, Eschatology, p. 230)
**CCC 1060 **At the end of time, the Kingdom of God will come in its fullness. Then the just will reign with Christ for ever,
glorified in body and soul, and the material universe itself will be transformed. God will then be “all in all” (1 Cor 15:28), in eternal life.
There is no Purgatory after the General Judgment at the end of time. Final purification will all take place before we enter into Heaven. Since at the end of time and General Judgement, all either go into Heaven or Eternal Condemnation, there cannot be any Purgatory AFTER the General Judgment.

REVELATION 20:12-15, 21:1-5a** 12 And I saw the dead, great and small, standing before the throne, and books were opened. Also another book was opened, which is the book of life. And the dead were judged by what was written in the books, by what they had done. 13 And the sea gave up the dead in it, Death and Hades gave up the dead in them, and all were judged by what they had done. 14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire; 15 and if any one’s name was not found written in the book of life, he was thrown into the lake of fire. 1 Then I saw a new heaven and a new earth; for the first heaven and the first earth had passed away, and the sea was no more. 2 And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband; 3 and I heard a loud voice from the throne saying, “Behold, the dwelling of God is with men. He will dwell with them, and they shall be his people, and God himself will be with them; 4 he will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain any more, for the former things have passed away.” 5 And he who sat upon the throne said, “Behold, I make all things new.” . . .
CCC 1038 The resurrection of all the dead, "of both the just and the unjust,"623 will precede the Last Judgment. This will be "the hour when all who are in the tombs will hear [the Son of man’s] voice and come forth, those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of judgment."624 Then Christ will come "in his glory, and all the angels with him. . . . Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats, and he will place the sheep at his right hand, but the goats at the left. . . . And they will go away into eternal punishment, but the righteous into eternal life."625
CCC 1042 At the end of time, the Kingdom of God will come in its fullness. After the universal judgment, the righteous will reign for ever with Christ, glorified in body and soul. The universe itself will be renewed:
The Church . . . will receive her perfection only in the glory of heaven, when will come the time of the renewal of all things. At that time, together with the human race, the universe itself, which is so closely related to man and which attains its destiny through him, will be perfectly re-established in Christ.631
**CCC 1043 ** Sacred Scripture calls this mysterious renewal, which will transform humanity and the world, "new heavens and a new earth."632
It will be the definitive realization of God’s plan to bring under a single head "all things in [Christ], things in heaven and things on earth."633
CCC 1044 In this new universe, the heavenly Jerusalem, God will have his dwelling among men.634 "He will wipe away every tear from their eyes, and death shall be no more,
neither shall there be mourning nor crying nor pain any more, for the former things have passed away."635
CCC 1045 For man, this consummation will be the final realization of the unity of the human race, which God willed from creation and of which the pilgrim Church has been "in the nature of sacrament."636 Those who are united with Christ will form the community of the redeemed, “the holy city” of God, "the Bride, the wife of the Lamb."637 **She will not be wounded any longer by sin, stains, self-love, that destroy or wound the earthly community.**638 The beatific vision, in which God opens himself in an inexhaustible way to the elect, will be the ever-flowing well-spring of happiness, peace, and mutual communion.
I think we know too little about the afterlife to know for sure. Could Purgatory be “temporarily” maintained after the Last Judgment until the last soul exits it, Purgatory is not IMO an option that you can simply get rid of out of necessity, as “nothing unclean will enter the presence of God in Heaven”. Or perhaps God will choose to give a grace of instant purification to all those who won’t have “spent” enough “time” in Purgatory to satisfy God’s justice and to have cleansed themselves of their attachment to sin. I don’t see a third option, not saying there isn’t.
