so after i got this error i searched all of the internet, I reset nvram with pressing those keys, and started it in recovery mode, so when I go disk utility in recovery mode I can first aid them but It doesn't change anything, after this i discovered in the internal thread of disk utility under apple ssd there is a grey writing and when i click this i saw no available area and it's full of others, i tried to erase all of the things and install macOS again but i cant erase anything. i don't know what to do anymore.
i can send pictures if anyone wants.
