Muse Animate - can't import the package with Unity 6 preview

Hello,

I am playing with muse packages. I’ve been able to import all of them successfully except Muse Animate. I actually have the following error:

Can someone help me resolving this please? I tried uninstalling all, or even install the package manually from the cache directory on my disk, but nothing works.

Best regards,
Jérémie.
