Cubase 4 essential - Halion - can't open the SW yet

Hi at all, I really open to find a solution here…
my Cubase Essential 4 has worked regularly until a few days ago…

Probably intend of some upgrades on my MacBookPro every time i try to open my software the process will go down (please take aloof to the screenshots attached.
The trouble is about Halion 5 but the thing is that I don’t have and I don’t want Halion 5. I’ve always worked with HalionOne that was pre-installed in my SW with regular license…

How can I return to utilize my software ??

I need to work on my production and it’s very frustrating cause Steinberg told me that Cubase Ess. 4 is no longer supported…

Thanks for anyone that could help me to find a solution
