Luckily I managed to solve this problem by downloading Waves .appx file from https://store.rg-adguard.net/ (using url:https://www.microsoft.com/store/apps/9pjppgg8tgvg).
Now I needed to download Appx dependencies. I used this link for that purpose https://github.com/j00sean/SimpleWebView/tree/master/SimpleWebView/AppPackages/SimpleWebView_1.0.0.0_Test/Dependencies.
Then I just ran "Add-AppxPackage -Path "Path\to\File" in Powershell, for every package (Framework, Runtime, VCLibs, Waves).
After connecting jack I was greeted by Waves window, prompting me to select device type.
