Is it a real paradox what we're facing?

A lot of people are losing their minds over this in different forums, websites and in youtube, but is this a real paradox?

It seems like the events that ended up creating Black are completely unrelated to Trunks, which means that his current actions with time travel don't matter.
Even if Black is present Zamasu, the events that created him are still completely different from those in the main timeline (except for the fight).

What we know is that Black traveled to Trunks timeline, making him go back to the past, wich leave us three different posibilities:

1.Black is present Zamasu, he succeed in killing Gowasu and taking Goku's body. When Trunks changed the past, Black and his actions were protected by the time ring, wich is why he still remember the events that created him, as simple as that. But it would be an incomplete explanation, as we would still not know what made Goku fight Zamasu and the time rings would be even more mysterious.

2. If we use the pre stablished lore, Trunks should have created another timeline as he changed history (again). This could make sense as Black said that he's the one that fought Goku but he didn't state anything more, so he could be from an "original timeline" that splitted with Trunks's actions. But that would also mean that a new time ring should appear so either things must be explained in the future or this is an inconsistence.

3. This is a plothole. Not because there's a time paradox but because if we follow the pre stablished lore, Trunks should have found out that Goku and his family are dead, making things confusing for him and the Z gang (if they weren't killed) as nobody could possibly know what happened.

I can see plotholes but no paradoxes, what do you think? (sorry for making another thread for this)
