Problem with Groupshare after last update (Studio 2022)


I am contacting you because of a problem regarding Groupshare that I have experienced since last Friday, after installing the last update.
When I try to open the project after importing it:
1) First, I receive the message "Object reference not set to an instance of an object"
2) After some attempts, I receive the message "User XXXX (my username) not found" (even if I am correctly connected to the server).
Last Friday my client's tecnician tried to fix the issue by connecting to my pc via Teamviewer, but it didn't work, so he sent a ticket to RWS.
Since I have a PLUS licence, I tried to use the laptop, where I hadn't installed the last update, and there it seems to work. So I suppose there is a bug in the update. Did anyone experience the same issue?
