What did you do?

package main

import (
	_ "github.com/ipfs/go-ds-leveldb"
	_ "github.com/libp2p/go-libp2p-kad-dht"
)

func main() {
}

When go mod tidy is executed, the versions of the two packages are:

require (
	github.com/ipfs/go-ds-leveldb v0.5.0
	github.com/libp2p/go-libp2p-kad-dht v0.21.1
)

Try to update github.com/libp2p/go-libp2p-kad-dht, panic appears:

> go get -u github.com/libp2p/go-libp2p-kad-dht
panic: internal error: can't find reason for requirement on github.com/syndtr/goleveldb@v1.0.0
