This problem was observed at a customer that had Trend Micro antivirus running.
Just connecting to metadata (after entering login) could take several minutes.
Loading the project - well, we had better things to do.
When we turned off Trend Micro antivirus, all worked normal.
- Turn off the antivirus system, or the parts hereof that cause the problem, or
- Add the Acinta applications to the antivirus system's "White-list"
