Error: Request method wallet_* is not supported

[CiprianDraghici]

I am trying to switch the Metamask chain. If the chain is not available then I am trying to create one,
but no request is working.
Some references:
https://docs.metamask.io/guide/rpc-api.html#unrestricted-methods
https://docs.cloud.coinbase.com/wallet-sdk/docs/switching-chains

For the majority of users everything is fine but there are a few of them that have this strange error:

They have the latest version of the Metamask extension.
I can't reproduce it on my machines (macOS 13.2.1 and ubuntu 22.04)
Does anyone have any idea why this is happening?

The issue was triggered because of multiple wallet extensions installed on the same browser.
