Terraform plan failing on PR due to state lock, but apply works?

Running into a weird issue with our GitHub Actions workflow. The terraform plan step on the PR keeps timing out waiting for the state lock, even though no one is running apply. Yet when I manually run apply in the terminal, it grabs the lock fine. Is the provider holding the lock too long? Here’s the action config:

- uses: hashicorp/github-action@v3
 with:
 configuration_directory: genesys

Any ideas why CI is blocked?
