I think you forgot what God tells Daniel in verse 1 which sets the context for chapter 12.
And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.
I’m not going to post an entire commentary on verse 1a because it really is self explanatory. Knowing the Preterist fabrication about it, I’ll debunk it if and when it arises.
What is it about the first century that seems so significant that ALL prophecy is fulfilled? Like so many others you put your entire belief system on ONE word, just like the word “shortly” of Revelation 1:1 which is a poor translation of the word tachos - which is coupled with the preposition (en) or ‘with’ - better translated “with suddenness.” (with swiftness)
But thou, O Daniel, shut up the words, and seal the book, even to the time of THE END: many shall run to and fro, and knowledge shall be increased.
How could Daniel seal up a book until the time of the end? The words ‘shut up’ - catham - and the word SEAL - or chatham are similar. Shut up means to 'stop, keep close and hide. ‘Seal’ means to restrain, hinder, or instruct. Daniel is told that the book is to be keept safely -preserving it until the time of the end when it would be authenticated and fully understood - at the time of the end. AD 70 was NOT the time of the end in an apocalyptic context.
Job uses the word ‘seal’ quite a lot. When he said in 33:16, “he seals up their instruction,” Gesenius says he means to, “instruct them privately and to reveal to someone.”

Another part of verse 4 that you’ve overlooked - which outright debunks Preterism is -
many shall run to and fro, and knowledge shall be increased.
I don’t know how preterist work their way around that in an AD 70 context but we’ll find out! Daniel is describing a distinctive feature of the time of the end. To run to and fro likely indicates a time when several modes of travel is widespread - and knowledge SHALL BE INCREASED implies an outbreak of vast information - a time of so many forms of media - just like we are participating in right now.
Daniel 12:4 But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.
When I look at Daniel chapter 7, 11 and the remainder of Chapter 12, we are obviously dealing with the tribulation period of the last days. NOT what occurred in AD70.
A time where the saints are given into Antichrist’s hands, the duration of “the time of trouble” for Israel. (a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.) The period that the holy city will be tread underfoot by Gentiles, also mentioned in Revelation 11. ETC.
Revelation 22:10 And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
In this context Preterism makes no sense. The nearness of time is not meant because Revelation was written between 90-95 AD. Preterist changed the dating of the book to fit their heresy to about AD65. Even if that were true, what nonsense to think that an entire book of 22 chapters full of symbolism would somehow be preached, copied, circulated, or even remotely understood throughout the world at a time of severe persecution within just a few years? That makes the entire book of Revelation about useless!
What Jesus is telling John is to not keep the book secret and security so as to postpone its understanding of its disclosure.
"The time is at hand" -
The word time is in the interlinear better translated as an ERA, and according to chapter 22 culminates when the last judgment takes place.
