damccorm opened a new issue, #20774:
URL: https://github.com/apache/beam/issues/20774

   We were using Beam v2.23 and recently, we are testing upgrade to Beam v2.26. For Beam v2.26, we are passing \--experiments=use_deprecated_read and \--fasterCopy=true. We run into this exception when we resume our pipeline:
   ```

   It looks like it is not able to deserialize objects from our existing checkpoints.
