If at all possible, I would recommend disconnecting your downspout from this and running it to somewhere far enough from your house that it doesn’t cause you problems.
This could be to ground, or to a soak-away, but ideally somewhere at least several meters from your house and where the natural grading conveys storm flows away, and not toward your house.
I never recommend roof leaders connected directly to a drain (and this drain seems terrible in its own right). This is because sediments and organics and roofing materials among other stuff inevitably end up going down the spout and prematurely clogging the drain.
If you have to have this downspout connect to a drain, I would recommend that you have an intermediate catch basin before flows go into a drain or further underground conveyance. This way with annual maintenance you can clean out all the crap before it gets out of reach.
The clean out suggestion I saw from another is not a bad idea, but may just push the problem further down the line (unless close enough to that grated basin I see in one of the pictures that it can push all the crap there).
As for the existing drain area itself. If the general area around there has flooding issues, I would recommend a perforated PVC pipe (holes pointing down), graded towards that grate at 2%, encapsulated in clear drain rock and wrapped all around with non woven geotextile.
If the only reason the area has water issues is because of the roof leader, then I would just run a non perforated run of PVC pipe to the grated area (but again, only if you can’t discharge it to ground somewhere better as mentioned above).
