Unable to confirm Super Admin assignment — confirmation button not working

I’m trying to change the roles within my organization. I am currently a super admin and would like to add another user as a super admin.
When I attempt to confirm the action, a screen appears asking for my password to verify my identity. However, when I click the Confirm button, nothing happens.
Additionally, I noticed that the password field shows the text in plain view by default (although it can be hidden), which seems unusual.
Could you please look into this issue?
