Stuck at boot

Hello

Anyone that can help med I'm stuck at boot an can't boot in safe mode either.
I am running Clover boot loader with internal graphics on Catalina.

Everything worked perfectly for a long time until my kids turn of the power to my pc then the bios got messed up but got it working again by updating the bios and then it worked for a while and now I hade to do a hard restart because nothing was working and know I get get in anymore.
