I believe there is a problem with Marin since the update, when I try to do it the game gives me an error message, the same for the list of waifus in the scroll.
Little edit for more content, the problem is in the shop too, and in the lastest version, someone can tell me how solve the problem by myself or if it's going to be clear ?
I'm getting the same issue. Judging by the error message it seemed to be whenever Marin had a voiceline. If you keep clicking ignore you can still see the still images/animations but it will continue to error for each screen that Marin would have dialogue.
Edit: It appears the bug is fixed in v0.98 according to the patch notes
