I found a way to by-pass anticheat and access the official realm without any restrictions what so ever on two seperate linux devices. I launched the game with its default launcher on Proton 8+. Proton starts to install microseft edge WebView2, as soon as I was able, I canceled the installation. Then, I switched the game's launcher to temporary launcher by-pass and launched again the game on Proton 8+, checked the By-pass launcher option (not the DX12, this doesn't work) and the game accessed the official realm with the progression I had since I lastly played on Windows.
