Cannot run project with Rider 2023 and dotnet-8.0 on Ubuntu 22.04.3

I had dotnet-sdk-7.0 installed and everything worked perfectly. Yesterday I installed dotnet-sdk-8.0 from the Microsoft package repository removing the existing .NET packages from my distribution first: sudo apt remove 'dotnet*' 'aspnet*' 'netstandard*'
And now Rider cannot run my project.

My system: Ubuntu 22.04.3 LTS

dotnet --info:

    Until someone posts a correct solution I'll present a temporary one. First of all, add an env variable:

    DOTNET_ROOT="/usr/lib/dotnet"

    Also, check that project properties are correct. Right-click on the folder with the project and select "Properties". Set the correct checkbox for "Target Framework". enter image description here It looks like the command sudo apt remove 'dotnet*' 'aspnet*' 'netstandard*' leaves some artifacts from the dotnet-sdk-7.0.

    Got exactly the same problem. For me solution was to edit

    /etc/dotnet/install_location
/etc/dotnet/install_location_x64

    /usr/share/dotnet instead of /usr/lib/dotnet

    After that change everything works great.
