Android 10 emulator - unable to uninstall apps due to Invalid UUID string

I'm trying to figure out if it's just me. On latest Android Studio and Emulator, a stock Android 10 (API 29) image is not able to uninstall apps due to the exception

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.google.android.packageinstaller/com.android.packageinstaller.UninstallerActivity}: 
 java.lang.IllegalArgumentException: Invalid UUID string: 1BE9-1809

Any hint would be welcome, please note

• uninstalling through ADB adb uninstall works as expected, but I need to uninstall through standard drag-n-drop
• already took a look at this SO thread (Invalid UUID of storage gained from Android StorageManager?) that leads to believe it's because of the naming of the virtual SD (but I can't create an instance without such SD, at least from Android Studio)

Full stacktrace:

thanks!

dumb workaround: delete/rename sdcard.img in emulator instance so that it cannot be mounted anymore ie. rm ~/.android/avd/Pixel_3a_API_29.avd/sdcard.img
