Hello Moritz,
First a pop-up came about not finding it, so reinstalled it.

Could you provide the first lines of content of test.csv ?

So you have over 1.5 billion cells. That's quite big, but not impossible
to handle. Depends on your machine.

You only have 12901 segments, so an average size of 32822m2 per segment.
Is this what you aimed for ? As you asked for a minsize of 5000 pixels I
guess this is deliberate.
You threshold of 0.25 is also very high...
