mac reset problem

hey, i need help,

it's long time i install OpenCore and i didn't have any problem with that but after install the last update, when i want to connect my account the screen don't worked and i can't seeing anything, so i tried to reset my computer because i didn't have a lot of information on but since that i have this picture and i can't do anything...

You can tell me what i can do ?

Other information :

when i press R and shift, it's working but can't connect on the internet even if i write the right password it doesn't work ...

i didn't save my mac because I was thinking it was not important (not a lot of data )

(my mac is a 2014 mac)

thank you for helping me.
