Thank you for providing the update. That looks like a lot of work was done!
A gasket for the oil sump looks like it's replaced two different past part numbers.

I have the same oil leak just at the 2500km. It was made by the Jan 2024.

We can see the oil pan just under the engine .

So why do they pull the engine out to change the oil sump gasket?

I am confused.

January 2023 or January 2024?
