EDIT : to reproduce this you can try to connect and disconnect multiple times and restart your Dapp sometimes when you disconnect a wallet it will happen

I did more testing and I reproduce it after connecting and disconnecting wallet for 10 - 15 times, did hot restart sometimes and re debug app 2 - 3 times
it's hard to reproduce but QA reported sometimes it happen on first run of app

I checked when it's happening _client.connect doesn't give response and we doesn't have URI or any error

Thank you for the bug report, I'll be looking into it.
