AirGap vault, stuck in 'Enter Password' loop

Good afternoon,
I am using both AirGap Vault & Wallet on the same device. I am trying to transfer my AE from the wallet to another address, but I can’t sign the transaction in AirGap Vault. The app asks me to ‘Enter your Password’ but to be honest I don’t even know to which password it’s referring to.
Anything I enter, when I click ‘unlock’ the dialog just disappears and nothing happens. Here’s a couple of screenshots:

I am happy for any help or pointer how to unblock this.
