Admin page shows errors after upgrading to v3.5.3

The admin page is showing errors after upgrading from version v3.5.2 to v3.5.3

And reports the following error:

loader.js:247 Uncaught (in promise) Error: Could not find module discourse/admin/models/admin-plugin imported from discourse/plugins/docker_manager/discourse/models/repo

It works normally after disabling plugins, but I can’t pinpoint which plugin is causing the issue. Can you help me take a look?

The issue persists when “Disable unofficial client plugin customizations” is enabled in Safe Mode, but it works correctly when “Disable all client plugin customizations” is enabled.

3.5.3 is no longer supported. Please see https://releases.discourse.org.

As Nate said that is a very old version now. Maybe try a command of ne update.
