Hey @Saface89 ,
Please excuse us for the delayed reply. It seems you've hit this issue. Can you try setting ANDROID_AVD_HOME as described in this comment and see if this will resolve the issue on your side?

Hi @Saface89,

We were able to reproduce the issue and open a PR with a fix. Most probably it will be officially released in NativeScript 6.3.1 in a few weeks.

As a workaround, you could pass the identifier of the emulator image to your tns commands. For example: tns run android --device Pixel_API_29.
