Thanks for reporting this. I have been able to reproduce the issue and know why it is happening.

The root cause is that:

1. A lot of visualizations indicate that they require bundles from visAugmenter
2. visAugmenter requires bundles from savedObjectsManagement
3. savedObjectsManagement requires the management plugin.

As a result, if management is disabled everything falls apart.

Sadly, the code doesn't validate transitive requiredBundles for excluding a plugin and if it had, all the visualizations that need visAugmenter would be disabled. But because it is not, OSD is allowed to start with them enabled and then it fails on the front-end.

If you require disabling management, the solution is to not upgrade to 2.9.0 until this can be fixed.

@ashwin-pc This can be closed via #4891, right?

Yes fixed. Follow up issue made for adding functional tests.
