@sailaxmanr83887909 Are you expecting for assets to automatically get published? This is not by design. Assets will publish when a user clicks to Activate it or activate a page with assets in it.
Can you test in AEM6.5? I found an issue was resolved in AEM6.5 which may be the same. If you still have issues in 6.5 it will be good to setup debug for workflow and perhaps open a Daycare ticket.
To clarify OOTB bundles are fine but your bundle stays in Installed state? If so then you will have to update the bundles in your project to match the ones that are updated in 6.4SP5 which is 2.20.
For assets it's the movewizard [1]. You will have to see if it's the same or look for the projects one. [1] /libs/dam/gui/coral/components/admin/moveassetwizard/clientlibs/js/wizard.js
Move/copy can be an expensive operation. You should take threaddumps [1] to see what's taking so long and perhaps enable debug logging for query [2] to see if anything can be done. [1] Take thread dumps from a JVM [2] Oak Queries and Indexing
I suggest you log a Daycare ticket with this info along your configuration info for search&promote. We'll check further if it's an AEM issue or check with S&P team.
