I would say its biased and trying to confuse people, since Christians know there book is corrupt so instead of removing and making sure wrong theologies and ideas are not derived from it they attack the other religion, happening for centuries.
Quran being not corrupt is not because of Muslims, its because God mentioned in Quran that he will protect it, reason being its the last message and if its not also protected than later generation on day of Judgment will complain that if we did not receive the instruction than how should we find the truth compared to previous generation who has Prophets amongst them ( though Muslim have not done a good job of sharing and living by that message)
Basically three points are raised in the video.
1) I would not much comment on Pharaoh asking Haman to make a tower ; ( basically he is boasting in front of Moses that I will go into that tower and see your God , since I think Moses said earlier that his God is the creator of earth and sky) but make sense he meant a long building so he can go into sky and meet the God, so if he did not say Pyramid its not an anomaly IMO , Pyramid were never meant to be climbed and sky highs?
2) Most of the historian take Dhu-al-qarnayn as Cyrus ( a Persian king) who built the Iron wall not Alexander ( who as per my knowledge was not a pious ruler and does unjust killing etc) , Character of the person in that chapter reflects of a moral King who travel in three directions on its military campaigns. ( so person in the video is lying on this one)

3) Quran says Joseph was sold for silver coins ( They later sold him for a cheap price, just a few silver coins—only wanting to get rid of him )
no word of Dirham etc , and Silver coin has been used for a while , so for e.g below link says since 2000 BC ( I am not a historian but you can google more) ; than again Plausible and not an anomaly.

The above issues raised are not common issue raised in Quran , here are few which a new revert is talking about and trying to debunk, https://www.youtube.com/watch?v=W2seyQe9YG4&t=434s ( thought to share since recently saw it partially)
i guess we should be interested in the belief concept of a religion, does they sound logical, and help answer relationship between human and universe, human and God, human life , talk about Balance, Justice, Equality , Morals
The historical events listed in Quran are more for a believer to understand how humans/civilization in past has acted in certain situation , especially Jews and Moses are mentioned more in Quran than Muhammad because God wanted to teach new believers to not become like them and don't uses those tactics to get away from the moral code set out for them ( unfortunately Muslim did not took much of those lessons)
