Issue with go1.21 and log/slog package

[kikihakiem]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've read the typecheck section of the FAQ (https://golangci-lint.run/usage/faq/#why-do-you-have-typecheck-errors).
• Yes, I've tried with the standalone linter if available (e.g., gocritic, go vet, etc.). (https://golangci-lint.run/usage/linters/)

Description of the problem

I'm facing an issue after upgrading to go1.21. Got an error saying:

ERRO Running error: 1 error occurred:
        * can't run linter goanalysis_metalinter: buildir: failed to load package : could not load export data: no export data for "log/slog"

It was running fine with go1.19 and go1.20. I tried both the binary release (v1.53.3) and build from the source using the master branch.

Related to #3933

Hello,

I'm not able to reproduce the problem.

module github.com/golangci/example

go 1.21

package main

import (
	"log/slog"
)

func main() {
	slog.Info("Hello world!")
}

The problem was because the GOPATH pointed to the root folder of go1.20 even though I used go1.21 binary. The issue is fixed after I updated the GOPATH to go1.21. Thank you for your swift response @ldez !
