Viber become Blank page

I have an issue with Viber desktop. After updating my Operation System OpenSuse Tumbleweed, my Viber for desktop become blank page. I can access only the button for minimize, maximize and close. Do you have any idea about this issue?
As addition information, I have been installed my application from the flathub.

After updating new version of flatpak package, everything is working as usual.

I’m glad to hear that. And thanks for reporting back.
