My wireguard install has broken and I'm unable to fix it
According to gdayhowyagoin on reddit , wireguard-go version 0.0.20210212 is the culprit. If you're using brew, you can see how they downgraded it, but if youre using macports, you can follow this:
git clone --single-branch https://github.com/macports/macports-ports.git
cd macports-ports
git checkout e01555c11df59855b73fd540accc778a41145bf8
cd net/wireguard-go
sudo port install

I hope this clears your issue.
