After upgrading to Catalina, I entered the system, stuck in the login interface, and the system lost response, but I can enter from safe mode, my motherboard is B360, CPU: I7-8700, SSD Intel. Thank you very much for your help.

In the login interface, my keyboard and mouse lost their response, and the system seems to have lost its response, because the clock on the interface stopped, I entered in safe mode, everything is fine.

I am definitely not the error that occurred during the update process. I updated successfully. After the restart, I stuck in the login interface. The system lost the response. I used the DVI interface to reach the login interface. I used the HDMI interface, and the black screen, my Clover 2.5 5027. version. My computer is a desktop

Me too : after upgrading to Catalina, only safe mode is possible

Could be incompatible kext. IIRC Safe mode prevents those from loading.
