According to Yarn documentation, that error code is YN0018 - CACHE_CHECKSUM_MISMATCH

Try the following:

1. Clean Yarn Cache Locally

yarn cache clean --all

2. Update Checksums

For Yarn v2/v3:

3. Commit and Redeploy

I think the reason for this is you forgot to add your lock file, the current package and lock is not matching.

hope it resolves your issue.
