I also have a local test install of B1449 and it doesn't have this problem.
The Portable NAS is installed to \\DS410-1\CEJROOT\PGMS_WIN\MMV4-DS410 and NOT a mounted drive letter. I have been doing this since the early 1420's builds with no problems. I reverted back to MM B1448 and MM worked normally again. I then reinstalled B1449 and the problem occurred again only on the second and subsequent startup attemps.
I downloaded and ran debugview and these are the last lines in the file:
