Hmm, I don't know enough to give you a confident answer yet. However, based on the information extracts, it seems that some users have experienced similar issues after upgrading Airbyte. In some cases, reconfiguring the connections or sources helped resolve the issue. It's also worth noting that some users reported issues with specific versions of Airbyte. It might be helpful to ensure that you're using a stable version of Airbyte and that all your connectors are up-to-date. For more detailed guidance, you might find the [Airbyte documentation](https://docs.airbyte.com) helpful, particularly the section on [upgrading Airbyte](https://docs.airbyte.com/operator-guides/upgrading-airbyte/).

I'm also trying to downgrade, but not sure how (changing the .env var doesn't help)
