1Password not usable with Kubuntu Plasma (Wayland)

I tried to switch from Password Safe to 1Password because the company account includes a family account. 
Under Kubuntu 26.04 Plasma desktop with wayland I cannot signin in 1Password because of a lack when using keyboard input or mouse input. The QR code is useless - half of it is greyed out.
Is anybody else using 1Password with Kubuntu?
After reboot the application crashed. 
Is it working under Gnome or other desktop environments?

Greetings
