[BUG]: Auto Degradation of Azure Self-Hosted Agent from v4.253 to v4.252 upon upgrading.

[pratiksoni1408]

What happened?

Performing a manual download from https://github.com/microsoft/azure-pipelines-agent/releases for Azure Self-Hosted Agent v4.253.0 Windowsx64.

Configured the agent v4.253 in my Azure DevOps Organization (ADO Services). It shows the correct latest version in Azure DevOps UI for my newly configured agent.

However, old agents are not getting upgraded from v4.252 to v4.253 in ADO UI when I hit "Update All Agents". Additionally, when clicking on update all agents it downgrades the latest version to v4.252 for my new agent.

Powershell command line logs:

Downgrading agent to a lower version. This is usually due to a rollback of the currently published agent for a bug fix. To disable this behavior, set environment variable AZP_AGENT_DOWNGRADE_DISABLED=true before launching your agent.
Agent update in progress, do not shutdown agent.
Downloading 4.252.0 agent
Waiting for current job finish running.
Generate and execute update script.
Agent will exit shortly for update, should back online within 10 seconds.

There's an ongoing bug in v4.253 that is forcing it to lower down to the version v4.252.

Requesting to fix the bug sooner so that we see the new agent version in place.
