Solution

It seems that upgrading android studio (4.1.2), the emulator, and SDK tools fixes the issue since 2021.

After updating Android Studio, go to the preferences for Android Studio > Appearance & Behavior > System Settings > Android SDK > SDK Tools (tab) and select Android Emulator (I used 30.3.5), Android SDK Tools (26.1.1), and maybe the Android SDK Build-tools.

Disclaimer: These steps solved it for me. It might well be that only updating the "Android Emulator" SDK tool would have been enough.
