PureData questions

Hello everyone.

Can I use Gem with PureData if I use this integration?

I can’t see Puredata opening from a .pd patch inside Ossia Score, I just get a black window.
Why?

Note I’m using Windows 11 and the latest Score download from Ossia.io

Thanks in advance for any kind of support.
Regards, have a nice day.

Kindly, Ivano.
