4. Close Unnecessary Background Tasks
Another thing you can do is simply close unnecessary background tasks on your PC to ensure there is no additional consumption of system resources happening in the background whatsoever.

A slower internet speed or unstable connectivity can cause issues with the game launching or fetching data from the server. You can also try switching the internet connection from wired (ethernet) to wireless (Wi-Fi) to cross-check the network connectivity problem.
If your IP address has some issues or your DNS address is troubling you a lot then make sure to use the Google DNS address on the PC to avoid rubberbanding connection or stuttering or even lagging issues which can happen due to slow internet.
