7Z compression password issue [BUG]

Configuration

• Keka version: [e.g. 1.1.24 (3421)]

Describe the bug

I'm trying to compress and password protect a folder in Keka in 7Z format. I enter a password, drag and drop the folder in and save it to my desktop. However, when I try to open it, I enter the password in the field, press open and nothing happens. The window with the password in it pops back onto the screen.

Please refer to #477, Archive Utility is not compatible with AES-256, you need to extract the file with Keka.
