Was the .metadata edited somehow? It looks like an important file has been deleted.
No. I had not edited the .metadata.
It looks like someone else did tamper with the .metadata as the stack trace shows that the code is recovering from a missing hidden project in the .metadata. Marking as a dup of bug 241400. Please reopen if you have more information on how to reproduce this problem. *** This bug has been marked as a duplicate of bug 241400 ***
