Macintosh HD not found in recovery
I have done some extensive research and cannot find the solution. I am prepping my 2015 MacBook Pro for resale. I went to erase the hard drive using Command-R, but the drive is not listed (pic attached). However, if I let it totally boot up, it's there. So, what's the deal? I tried clearing the NVRAM, but no success. Can I please get some help? Thank you!
MacBook Pro 13âł, macOS 11.6
