This can be a sqlite problem. Recent sqlite refuses to open a database
file if any other file in the same directory is kept open by any other
application. This is a new feature of new versions of sqlite (not
GRASS), I remember that this was not an issue about a year ago. You
could check if you have any other application running that has opened
some files there, e.g. QGIS. Just a guess.
