I can confirm I have the same issue adding --legacy-peer-deps at least let you install the beta version

Same issue here

This will be fixed in the upcoming release (4.0.0-beta.11) linked above. As of Next 15.1, React 19 stable is used and our peer dependencies will be updated to reflect that.

[robcaldecott]

This change will be great, and for the benefit of others, you can also use a package.json override here instead of legacy-peer-deps.

Assuming you have react and react-dom 19 as dependencies:

"overrides": {
  "react": "$react",
  "react-dom": "$react-dom"
}

[gabor-at-reed]

"overrides": {
  "react": "$react",
  "react-dom": "$react-dom"
}

Or even more targeted:

"overrides": {
    "@auth0/nextjs-auth0": {
        "react": "$react",
        "react-dom": "$react-dom"
    }
}

This should now be fixed in the latest release 4.0.0-beta.11.
