Why ZecWallet didnt start?

Good evening,
I wanted to create a ZecWallet that supports Z-address transfers.

I downloaded ZecWallet Lite. Unfortunately, it cannot be opened, the picture remains frozen as seen on my screenshot.

Then I downloaded the ZecWallet Fullnode and even there the picture remains frozen.

You know what I can do about it, so that I can also use ZecWallet with z-address transfers.
