Cannot build subscriptions example

[0xtmphey]

After cloning the repo, running anchor build in subscriptions folder gives the following error:

Failed to obtain package metadata: `cargo metadata` exited with an error: warning: profiles for the non root package will be ignored, specify profiles at the workspace root:
package:   ~/Projects/crypto/examples/subscriptions/programs/subscriptions/Cargo.toml
workspace: ~/Projects/crypto/examples/subscriptions/Cargo.toml
    Updating git repository `https://github.com/clockwork-xyz/anchor`
error: failed to load source for dependency `anchor-lang`

Caused by:
  Unable to update https://github.com/clockwork-xyz/anchor?branch=0.25.0-solana.1.13.4#27531b40

I tried deleting Cargo.lock but then the build fails with different conflicts in dependency resolution.
