development – Android Studio: Can not add an SD card to AVD with the help of an external file

I just switched to a new laptop (migrated from Windows 7 to 10) and I now configure my development environment for Android. As such, I created a new AVD using Android Studio. However, I can not add an SD card with an external file, this option is grayed out. I use the same AVD configuration as in my old environment (except that it has just been created).

I've read that for some people, the option remained disabled until they ran the mksdcard tool. I have already done it and restarted, but I still can not add the SD card from my old device.

Also tried to create an AVD with different settings without modifications. Ideas?
