Hi Momento,

Here is a file that is hopefully close to yours. Note the XY plane orientation of the Spline Mask.

CV4_2023_drs_23_MOad_01.c4d

Do you use the desktop or the iOS version of Affinity Designer?

There are many more options with eps files, but since I do not have the exact exports, it would be guesswork, which I try to avoid here.
I have seen too many eps files that were not written well in the past 30 years. So, I have to buy Affinity if you have more questions.

Please share your target with this workflow so that I can better help.

All the best
