Unable to play Roblox Unblocked after recent changes

I'm having trouble playing Roblox Unblocked on my Samsung Galaxy Book 4 Edge. Earlier, I used a method found on by Infrexa and it worked for months. 

Meanwhile i moved another country and after being away for about a month, I tried playing again, but now it no longer works. Whenever i try to launch it ends with an error message "Can't connect to the internet", and Windows closes the app automatically. I raised this issue earlier but could not found effective and permanent solution.

My device is running Windows 11 (licensed) with all updates installed (16GB RAM, 512GB SSD, Qualcomm Adreno GPU). I also noticed memory usage becomes very high whenever I attempt to run Roblox Unblocked. Apart from that, I can't access Now.gg or even the official Roblox website from this device.

I've already tried reinstalling, restarting, and repeating the process many times, but nothing has fixed the issue.

Has anyone experienced similar issue on this device? Are there any other methods to get Roblox Unblocked working smoothly or resolve the memory/connectivity problem?
