Twitter images don't work anymore

Since today, no image on Twitter can be loaded. If I deactivate VPN, it works. I tried it with Firefox and Chrome, for both browsers the same behavior. On Chome for Android it works for some reason.

Does someone have the same problem?

Edit: For people having the same problem, the solution found by alexpartyman is to deactivate the newly introduced CyberSec function in NordVPN.
