There is no reason to update the dependencies locally. Upgrades can cause dependency issues, as you have found, and packages like go-ethereum commonly change their public-facing functions even in patch releases. Best to stick with the package versions as currently set in the repository.

We're also seeing this issue. It's not a matter of just not updating dependencies, adding go-ens to our project, then doing go mod tidy twice will reproduce the error.

Other packages also seeing the error: btcsuite/btcd#1839

TL;DR: Run go get github.com/btcsuite/btcd; go get github.com/btcsuite/btcd/btcec/v2

I have updated the dependencies for this module so that it uses the latest packages, which (assuming that dependencies have addressed the issue) should solve this. The release is v3.5.5
