I have had exactly the same problem for more than a year...
This problem this product or on my two HP notebooks with Windows 2004 (but already before 1909 and older) chrome extension several Vault synchronize...
I switched from webdav synchronization to folder synchronization, I completely uninstalled the application and reinstalled it, I tested with the store version and the exe version but the problem is still there...
This problem is also added to the problem on the mobile application that doesn't work, I have already contacted the support for this problem also I have sent the reports plus videos but I have no news...
I specify that I bought the desktop and mobile version and I'm excremently disappointed...
If a patch does not come quickly I go to the competition!
And all my customers where I installed it too..
