Rerun version

rerun 0.5.1 [rustc 1.69.0 (84c898d65 2023-04-16), LLVM 15.0.7] x86_64-unknown-linux-gnu, built 2023-05-21T12:49:02Z

Additional context
Using the runner as a library from my rust program works fine. This problem happens only with the runner installed by cargo.

Thanks for the report! This works on main, so this will be fixed by the upcoming 0.6.0 release

This could still happen for users using rerun as a dependency, but it should be properly fixed by #2198 now

[emilk]

Actually, this can still happen for users that do cargo update -p ctrlc. We should pin ctrlc
