Audirvana and LA Convolver

Hi,
Is somebody knows why LA Convolver is not working with Audirvana ?
On my Mac mini under 10.14, the Mac crash after 10 minutes.

Is it any other solutions to make something similar ?

Kind regards,
Bertrand

In 3.5.23 LAConvolver does not work here either. I do have only the left channel and sometime
Audirvana crashes.
