"Windows Audio Device Graph Isolation" takes up a lot of RAM

Hi there,
I have an issue with the Anki Windows version 2.1.37.
During study session the process called “Windows Audio Device Graph Isolation” takes up a lot of ram, more than 3 GB. The deck i’m using contains audio files, so it does make sense. Each card in the deck contains two audio files and the session usually consist of at least 75 cards. Here’s a link to the deck: https://ankiweb.net/shared/info/2141233552
The RAM also will not be freed up when Anki is closed, but the process can be terminated using Task Manager and will automatically restart.

I use anki as delivered from the page without any add-ons.
I’m on Windows 10.
