'mix hex.outdated' tells the 'Update not possible' for some libraries

When I changed these versions for {:phoenix_live_view, "~> 0.15.4"}, {:phoenix_live_dashboard, “~> 0.4.0”}`` ElixirLS tells this error on Visual Studio Code:

an exception was raised:
    ** (Mix.Error) Can't continue due to errors on dependencies
        (mix 1.11.2) lib/mix.ex:436: Mix.raise/1

Peek Problem (⌥F8)
No quick fixes available

So I tried to update even with those errors doing mix deps.get and mix compile…
It was needed to restart the ecto and the app phoenix liveview are working right and passing the tests.
But The ElixirLS continues raising this error…

Thank you all for the help, it was very helpfull!
