There was no need to remove (during remove products are always deactivated) and install eea again. After installation of gcc-12, it is enough to try again starting our service sudo systemctl start eea. 

Thank you, Kurco. You're lightning fast.
This helped.
this is the command order and installation file:
sudo apt install gcc-12
sudo apt-get remove eea
Then download the installer from eset and installed the AV with:
sudo sh ./eeau.x86_64.bin
After the reinstall activation was off.

Hi,
most probably you are experiencing issue with missing compiler. Ubuntu latest released kernel was compiled with gcc-12, but this version isn't by default installed there and it results into issue during our kernel modules compilation. 
Please try to install gcc-12 package (sudo apt install gcc-12) and start again our service. 
Regards,
Kurco
