@EA_Leeuw, thanks for your response.
I've already tried to repair via Origin, no error detected.
25 years of PC gaming i've tried simple things on windows to check my side (clean registry, scan for malwares or problems, etc. etc.)
No problem found on my PC and no effect on the problem.
The "Easy anti cheat problem" is random.
Yesterday i was unable to play (and quite scarde by the message) soo i posted here. I launched the game again 1 hour later afetr multiple checks on my PC, and had no problem (i've played 3 matches with friends in multiplayers).
But i went to diner and when i wanted to play again i've been kicked from solo / co op again by Easy. I just restarted the game and was able to play again....
From what i understand, I'm kicked after the round start, maybe 30secondes later. I can start the round but i'm kicked.
It looks like a comunication failure, Easy seems to ask for a response from my PC and no response is send or received (don't know where the message is lost) soo it kicks the player. Easy do not detect a problem, he react to a lack of response.
I don't think it comes from another program. My PC is quite old and i need to keep it clean to be able to play soo i can guarantee i have no mouse software, Onedrive or special anti virus filter interfering. I do shut down all "start with windows" options of my softwares to keep my PC fast and responsive.
For the ones who experience this problem i would suggest to exit game and launch again the game until Dice can fix it.
Boring but working.
And by the way, iv'e witness an old bug comes back... Game restart on 1st launch with reset of all parameters... When the "Epilepsy Warning" screen apears before launching the tutorial... and makes you cry for the 150th time.
Solution, go delete your "PROFSAVE" files ( in C: Users) corrupted to replace them by the ones you've saved previously to avoid getting mad and just uninstall. Because we wait for this to be patched since launch.
If you have no save... Well do again all the keybinding, check all parameters and options.. And after losing an hour doing soo, you'll get why you should save those 2 tiny Profsave files.
