I have the same problem in server action from RSC passing Next14 to Next15. But previously I fixed it on Next14 using try/finally :

Next documentation :

redirect internally throws an error so it should be called outside of try/catch blocks.

Next 13.4 Error: NEXT_REDIRECT in API routes:

export default async function Page() {
    let redirectPath: string | null = null

    try {
        //Rest of the code
        redirectPath = `/dashboard`
    } catch (error) {
        //Rest of the code
        redirectPath = `/`
    } finally {
        //Clear resources
        if (redirectPath)
            redirect(redirectPath)
    }

    return <>{/*Rest of JSX*/}</>
}

The only solution I can see is to return some typed error caught by all your server actions and pages to do the redirection on top level.
