Managed to find the root cause.

Tried running process monitor (procmon.exe) when starting the website. svchost.exe process is trying to create a folder in following location (C:\inetpub\temp\appPools) with app pools name.

And somehow there was a folder shortcut with name same as app pool. WAS process is trying to create the folder when starting the app pool. I have now cleared that folder and retried. It worked!
