Crashes at launch, File Corruption, Re-validating files over and over, Stuck at checking for updates when it does launch. However if you re-validate files and keep trying eventually it will let you in and plays fine. I've tried everything I can think of including reinstall the game and OS. What is odd is that it will repair multiple files, then need to repair more files a second time in a row. I can't be the only one. Google results have turned up little to nothing and logs haven't been helpful.
Neither steam or arch linux forums / discords have been able to assist. Hoping to find someone else who plays summoners war on Arch linux. I've found people in the game chat, but it's very hard to discuss this with them in game.
Steam overlay is disabled. Using Proton-Experimental has the most success for me so far.
