Tracks are empty after receiving via VST Transit

Hello everyone,
I hope someone can help me here:
if projects are exchanged via VST Transit, they appear in the recipient’s project, but the content of the tracks does not contain any midi/audio data. The project tempo is also not transmitted (but is synchronized and loaded according to Transit)
Audio files in the pool are also available, but with 0 sec. Duration !!??

Transmitter: MAC Book platform from 2010 (I7) - Cubase Pro 9.5 - VST Transit Vers.

Receiver: Windows 10 Cubase Pro 11 - VST Transit Vers.
From Windows to MAC - it works!

Where is the problem?
Thank’s for the Tipps!
