Unable to install on Debian 11 with Cargo 1.46.0

[Vicara12]

When I run cargo install pwninit I get

Downloads > cargo install pwninit
    Updating crates.io index
  Downloaded pwninit v3.3.1
error: failed to parse manifest at `/home/anon/.cargo/registry/src/github.com-1ecc6299db9ec823/pwninit-3.3.1/Cargo.toml`

Caused by:
  failed to parse the `edition` key

Caused by:
  this version of Cargo is older than the `2021` edition, and only supports `2015` and `2018` editions.

the output of cargo -vV is

 Downloads > cargo -vV
cargo 1.46.0

and system information is
