Please, i need some help.

I am stuck on the second reboot trying to install catalina update 10.15.4 over 10.15.3
After some minutes installing (progress bar moves), installation stops and this message is shown.

My system: MSI Z97 Gaming 5, Radeon RX 580, clover 5107 (Imac). Not able to boot into 10.15.3 anymore.

Thank you
Paul

the install process ends with the screen above shown.
