Video not rendering in InShot app

[hentsch]

Hi,
I don't know if it is the right place to ask my question. If not, ignore it and please, let me know where I can search for the answer.

I'm using WSA, installed from this repo.
I try to use the InShot app to edit some video. The app load well. But the video doesn't render, there is a black window instead of the video.

The same appends with LightCut.

Any idea ?
Thanks
Vince

Thanks @Howard20181 for your answer !
Neither InShot nor LightCut are present in the Amazon Appstore, so Microsoft probably won't reply, as it's not officially supported.
That's why I asked my question here...
Anyway, I'll report to MS
