No reply received so I decided to have few tests. Tested out by disabling many things which I had enabled and enabled few more which I wasn’t using. No luck!!!
Then I booted the machine with .iso. It picked my saved profile from local disk and booted normally. Error is gone!!!
I will check this scenario for few days more and then I will reinstall it on local disk.
Though it has broken my subscription license but it’s working atleast.
