Bug? Ctrl+D causes error in Visual Designer (B4A 11.80)

[asales]

I get this error when I try to duplicate a line in Visual Designer:

And this line in the logs:

[IDE message - 4:30:25]
An error occurred.
Referência de objeto não definida para uma instância de um objeto.

The line is duplicate, even with the error.

I don't see other behaviours, but this could be affect my project?

If this happens to you with any layout and any project, reinstall B4A, as B4A 11.80 works perfectly.

reinstall B4A

The problem remains, even with a new installation.
