Hi guys, not sure if this is right place to troubleshoot.

I'm implementing an app using Wagmi/Viem stack and having a WalletConnect connector. One of my user having this error on every of his devices (Windows desktop, Iphone). However, a friend sitting next to him on his mobile phone does not. (Meanwhile, I can't reproduce this on any of my personal/team devices , so it's really hard for me debug.)

Do you guys having any clue what's happened here?
