Current .NET SDK not supporting targeted .NET 7.0 of the ASP.Core Template

Hello there,
i had just downloaded this great template for Web project, but it seems i am getting errors concerning about the SDK version i am currently using. So i checked every project in the template and true all projects were mean to be using .NET 7. So having noticed this, and having all my previous projects build on .NET 6 i decided to download the correct version of the required SDK so i can start using the template. Done. But this didn't fix the issue.
So now i am having SDK version 7.0.404, which is the one required to use this template i assume, so i tried to set it by creating global.json in the solution's directory and setting used sdk to SDK 7.0.404. This made it even worse, so i deleted it. Here i am dead end. Don't know how make this template work and start building my project early on. I am just about to enroll in our web module so the problem i am encountering might seem stupid or probably there are things i am not aware of yet. Still i like mister Nikolay Kostov and company work and would like to use their template for my own first project because it seems pretty well organized and build.
Thanks for your time reader.

Start by reviewing the template's project files and the SDK version requested in the solution directory, then compare that requirement with SDK 7.0.404 and the reported build errors. Done means the template builds successfully with the documented .NET SDK setup.
