v3 causes a stack overflow, v2 does not

I'm updating my project to scc v3, which is rather easy, but it causes a stack overflow. This does not happen on v2. ``` thread 'tokio-runtime-worker' has overflowed its stack fatal runtime error: stack overflow, aborting ``` Here is the PR: https://github.com/moonrepo/moon/pull/2120 At first I thought it was the `iter_sync` calls, so I commented them out, and it still triggers. Not sure what to "try" and I'm not 100% sure which code piece is causing it. It looks to happen in a thread/task.
