Rhinoceros for MAC - installation problems on CATALINA

I’m having trouble installing Version 5.5.5 of Rhinoceros (5F96). It gives me error in the extraction phase of the update, without giving many explanations. I use a MAC BOOK PRO with CATALINA 10.15.3. Do you have any idea about it?

We’re not aware of any issues with 5.5.5 in Catalina.
I installed it myself just last week.

Perhaps you have a damaged download?

John, thanks.
I have no idea about what is happening. I start downloading from the old version of Rhino. An error occur during the expansion of the file
