First download a proper version of GoLand here — select .dmg (MacOS Apple Silicon) here (direct link — https://www.jetbrains.com/go/download/download-thanks.html?type=eap&platform=macM1&build=211.6556.11&code=GO).
Then make sure you are using arm version of go (
go version go1.16.2 darwin/arm64). If not, download and install arm version of golang (like «go1.16.2.darwin-arm64.pkg») from the list here — https://golang.org/dl/.
Now it should work.
With amd64 version of either GoLand, golang, or both, it will run as expected, but it will fail to debug in GoLand.
