New error after upgrading from Trados Studio 2021 to Trados Studio 2024

We recently upgraded both Groupshare (2017 > 2020) and Trados Studio (2021 > 2024) and now we are getting this error message (we are also Plunet users)

"The project cannot be opened because the following project languages are not supported on this computer" indicates that the software (like Visual Studio or Trados Studio) is missing the language packs needed to work with the project's languages. To resolve this, you need to install the required language packs for your software."
