bug(windows): Installation loop happens after clicking the OK button from the warning message during Galaxie Greek / Hebrew Keyboard installation

### Describe the bug

I noticed that while installing the Galaxie Greek / Hebrew Keyboard as the Fourth keyboard, I got a warning message 'windows has a limit of 4 custom 'transient' languages, and you may have reached this limit' in the Configuration dialog.

### Reproduce the bug

Here, What I did is:
1. Installed the latest Keyman 17.0.60-alpha build from Status Keyman site.
2. In the Keyman Configuration dialog, using download keyboard button, I have installed Khmer Angkor, Eurolatin (SIL) and Korean KORDA Jamo (SIL) keyboards.
3. Then, I tried to install Galaxie Greek / Hebrew (Positional) Keyboard.

I got a warning message 'Unable to install keyboard language; Windows has a limit of 4 custom 'transient' languages, and you may have reached this limit' appears with OK button.

Clicking on the OK button did not install the keyboard. Seems to be an issue.

I have attached the Screenshot as well as the Video file for reference.

### Expected behavior

Keyman Configuration should install Galaxie Greek / Hebrew Keyboard without showing any warning (?) message.
