App crash when set same symmetric key

[lmcmz]

Describe the bug

When I'm playing with demo app, the app crashed sometimes when connecting with demo dApp.
Is it possible to add try catch or throw here? without 2 force try in the code?
Or we can remove the the same key before we add it ?

@lmcmz thanks for bug report. Could you please attach detailed steps to reproduce crash. I tried your steps, but didn't catch the crash. I'm agree, we need to handle kms errors without for try, but looks like here something wrong in use cases

It's hard to reproduce, I just connect and reconnect the same wallet with the same dapp multiple times.
The duplicate pairing has been created, somehow, it crashes after scanning the QRCode.
