Issue first identified here: https://code.cryptopower.dev/group/cryptopower/-/merge_requests/1147#note_9091

How to replicate this crash:

  • Immediately the wallets load and appear on the UI, Click randomly at one of the synced BTC wallet and this crash occurs.

I got this crash:

As described here, this seems to be an issue on the neutrino v0.14.2 where different peers are resolving into the same IP address:
