@olivierlambert Same as the one mentioned by the OP: Error: buffer grain directory address is too short, expecting 8 minimum, got 0
@nraynaud Since my original VM had some confidential data I have created a new VM test in order to reproduce the issue. Well with this VM the problem does not occur even with XO 5.60. The only differences that I can think at the moment are Windows (before Windows Server 2019 and now Windows 10 pro) and the VMtools (before with tools and now without tools).
I will run more test and let you know.
