Thanks for your answer, it gave me an idea.
I uninstalled the windows application again, but this time I did it with software that cleans everything (registry key, etc.)
it worked, after reinstalling, I have access to the application again for a few days!
I do not know what happened. I looked at the settings, I must be alerted if I have no more storage space.
so this is not the reason for the bug, I still have space..
