When I try to add a term, the error "Object reference not set to an instance of an object." appears, and "No open termbase" is shown, even though a valid file-based termbase is shown in the project settings.

I'm using Trados Studio 2022 - 17.0.6.14902, with only file-based translation memories and termbases.

I have confirmed that the problem is related to the VPN. If I turn off the VPN (McAfee LiveSafe VPN), the termbase is correctly loaded and accessible.

Since I am using ONLY file-based resources and not server-based ones, why is the VPN causing problems? What data is being sent secretly to RWS? I use only file-based translation memories and termbases because my clients DEMAND it. If translation data is being sent to RWS, it would violate confidentiality agreements with them. If this cannot be solved, I will have to stop using TRADOS, and request a refund.
