Problem

The common coverage generation workflow doesn't work and returns error: Failed to load coverage: 'target/x86_64-unknown-linux-gnu/coverage/x86_64-unknown-linux-gnu/release/main': Malformed coverage data when running cargo cov -- show on generated by cargo-fuzz artifacts. However, when we had 2023-04-25 rust version, everything was fine.

Possible solution

Downgrade rust version
