how to fix this Error ?

having same sort of issue....have been disconnected with either ea server not avail or lost connection (my wi-fi did not drop) from squad battles matches for the past couple days. yesterday though I was disconnected from a preseason tourney live game and after I restarted, bc the game completely freezed up) I had the cheating warning with the additional message that I would be getting reduced coin rewards as a punishment (and contact ea etc. etc.). I absolutely did not disconnect on my end in any of these matches as I was either winning or in position to complete an objective (for example, I was well to winning 1 of my 16 squad battle matches on world class and was disconnected in the 2nd half so ended up getting 0 pts towards my weekly score instead of over 1k). bummer as I've heard same is happening with fc27 and I've already pre-ordered (for Nintendo Switch).

Hi there, sorry to hear EA FC 26 is crashing.

Could you please let us know:

• Are you playing through the EA app, Steam, or Epic Games?
• When did the issue start, and was it after any game, Windows, driver, or software update?
• Does the crash happen when launching the game or at a specific point/menu?
• What troubleshooting steps have you already tried?
• If you're on PC, please also share a DxDiag so we can take a closer look at your system and drivers.
