GHC Regression (GHC-87110) mixins not recognized, suggests package is hidden

Summary

Since Version 9.12.2 (did not test 9.12.1) calling cabal repl results in the following Message when using cabal mixins:

*** Exception: <interactive>:1:1: error: [GHC-87110]
    Could not load module `Relude'.
    It is a member of the hidden package `relude-1.2.2.0'.
    Use -v to see a list of the files searched for.

Hope this can be reproduced.

Steps to reproduce

see the following files for a minimal example:

example.cabal:

cabal-version: 3.4

app/Main.hs

module Main (main) where

import Example (projectName)

main :: IO ()
main = putStrLn ("Executable for " ++ projectName)

src/Example.hs:

module Example
    ( projectName
    ) where

projectName :: String
projectName = "example"

Expected behavior

I guess ghci should load without error when using mixins
