1. If you are using Blitz application, please uninstall it. This application is blocking the game for today. (Blitz.exe is able to record keyboard and mouse inputs, monitor other applications, and manipulate other programs)
Similarly, there will be a problem with starting the game if you happen to have a Riva tuner Statistic server. or Afterburner.and Nahimic2 apps from MSI You can remove each of these programs by add / remove programs but I personally recommend Revo - free version uninstaller which will thoroughly clean your computer of these applications
2. If you have Avast or AVG, uninstall it, or add Origin (Origin.exe file and OrigintClientServicem.exe file) and game to exceptions. These programs have recently started blocking Origin folders
Windows Defender for Windows or GateKeeper for Mac protects your computer sufficiently.
After uninstalling such a program, go to Origin. My game library - search for Fifa21 - right click on the game cover - Option: Repair
I don't work for EA
Same Issue have contacted support multiple times and most of the time they do not have an answer, They make me submit my dxdiag and still no news on this issue, Ive disconnected so many games just because in the middle of the game it freezes and then crashes, my Pc is well above minimum and recommended reqs. It is clearly an issue on there side but it seems they don't care about PC players. There is nothing about this on the trello board as well. Game is totally unplayable, just remove 5 matches from your div rivals, WL, and squad battles because thats how much it will ruin MINIMUM.
10 games in to WL and 3 crashes in the middle of games so far, was winning two of those. EA FIX THIS PLZ. Unbelievable how the game was released in this state.
