Mozilla VPN failing to open

Hello all, I've been happily using Zorin for a while now. I also use Mozilla VPN, which has been working fine. But today, the GUI has stopped working. When I try to launch it from the command line, here's what I get:

[21.04.2022 23:38:57.253] Info: (main - Command) MozillaVPN 2.8.0

From a bit of Googling, it looks as though this could be related to a GNOME update, but I can't find a clear suggestion as to how I might fix it. Any help greatly appreciated.

Thanks,
Jack

In terminal, what is the output for

ldd --version

These are minor warnings, but we can fix these up later, if you want.

It had to be current update coz mine is acting up also, refuses to open up.

I've had no luck with this yet, but for anyone who finds this thread, you can run the VPN on the command line with: mozillavpn activate

I'm seeing the same issue - immediately happened after updating to the last system update (after the 16.1 upgrade). The command-line method does work, but how can I verify this, since there's no GUI feedback anymore?
