Hello Socorro_14,
Does your Mac still start up to a blank screen now? If you're still getting a blank screen when trying to start up normally, there are some additional steps here that may help: If your Mac starts up to a blank screen
Just to confirm, did that error appear immediately after entering macOS Recovery? You can find some good information about macOS Recovery here: Intro to macOS Recovery
macOS Recovery is the built-in recovery system on your Mac.
On a Mac with Apple silicon, you can use macOS Recovery to repair your internal disk, reinstall macOS, restore your files from a Time Machine backup, set the security policy for different disks, transfer files between two Mac computers, start up in safe mode, and more.
On an Intel-based Mac, you can use macOS Recovery to repair your internal disk, reinstall macOS, restore your files from a Time Machine backup, set security options, and more.
If you need additional assistance, please contact Apple Support. You might be able to contact them here: Get Support
Thanks!
