ERROR cargo build sbf Failed to obtain package metadata: `cargo metadata` exited with an error: error: failed to load manifest for workspace member

I tried to build an anchor project

anchor init AnchorProject

cd AnchorProject

anchor build

Then This error appears!

admin@Desktop MINGW64 /d/folder_1/MY_Project/AnchorProject (main)
$ anchor build

Warning: cargo-build-bpf is deprecated. Please, use cargo-build-sbf

cargo-build-bpf child: 
C:\Users\admin\.local\share\solana\install\active_release\bin\cargo-build-sbf.exe --arch bpf

[2022-09-23T17:22:59.130309300Z ERROR cargo_build_sbf] Failed to obtain package metadata: 

`cargo metadata` exited with an error: error: failed to load manifest for workspace member

 `\\?\D:\folder_1\MY_Project\AnchorProject\programs\*`
    
    Caused by:
      failed to read `\\?\D:\folder_1\MY_Project\AnchorProject\programs\*\Cargo.toml`

    Caused by:
      The filename, directory name, or volume label syntax is incorrect. (os error 123)

and I don't understand what the question mark(?) in the above message mean!

note

I have solved the problem of metadata but when I return to build the project there is another message

$anchor build

error: no such subcommand: build-bpf 

Did you mean build-sbf?

also when I tried to write cargo-build-bfs there is another message appears

$cargo-build-bfs

Solana programs can not include rand as it would result in nondeterministic outcomes. Programs can not do I/O (files, screens, urls, websites, rand, etc., etc.)

See Rust program build restrictions:
