Mainform crashed when using Password Property

[L-Dlbcq]

Hello,

I'm developing a password manager and i encounter problem with it. As you can see in the following gif, I'm using a database file encrypted by password and i set a button to show the passwords. But if I cancel this, my principal window is crashing. Does someone encounter a similar problem ? Does exists a solution ?

Sorry for my bad english

Had same issue with MaterialTextBox so I had to change to MaterialMaskedTextBox and use passwordChar property
