Party not ready / Can't join or play after update

Exactly the same here !!!!

Welp. I'm having the same issues and still can't find a fix.

Hey everyone,

Thank you for hanging in there while the team's working to address some issues still popping up following the patch.

We'll provide further updates here and to the original post below as we get them.

We are aware of errors for some players as they transition between systems. We are actively working to address this issue and are hoping to have it resolved soon.

Edit: Shortly, players that have yet to update their game and are actively playing using Easy Anticheat will be kicked out of their lobby to force an anticheat update.

EA Javelin Anticheat is now live in Apex Legends

such a joke. can't even test something before launching it. a 30 second update broke the game. get good, EA

Hey, I'm having trouble getting into the match. I recently updated. Now I can't get into any match. Not even training. I keep getting Party Not Ready even though it's just me. I've tried restarting the application, I've tried restarting my pc and nothing is working. I wanted to know if there is a known fix 

When I logged in the game, even if I'm alone in the lobby it says Player not ready. I tried to restart the game multiple times but it is always the same. It happened just after I updated tonight.

Same here – "Party Not Ready," even though I’m not playing in a party or with any friends.

I'm experiencing the same problem. I don't understand how they can make the game worse instead of better.

Done all the stuff other people have. Repaired the game. Uninstalled jAvElIn, to have it reinstalled when doing a new launch. Tried the repair function in the uninstaller. Nothing works.

Sigh... 

Hello,

Since the September 29, 2026 update (Apex Legends PC switching to EA Javelin Anticheat), I have been unable to start any match.

Platform: PC ([EA app / Steam / Epic], Windows [version, check via winver])

Username: Lama62153

Game version shown: v3.0.2.44

SID (error screen): 2:1018423:11597049:9c50595e-5200-41a1-ad60-89dd97f5741e

SID (main menu): 2:1018717:11597049:ea3a56af-60a2-4d29-bc52-4e9fbecb66dd

Symptoms:

- When launching the game normally, I get the error: "The client is not running the anti-cheat module or failed anti-cheat authentication."

- When running the launcher as administrator, I can reach the main menu, but the game shows "Squad 0/0" and then "Squad not ready" even though I am alone and ready. Matchmaking never starts.

- No suspension or ban message is displayed.

What I have already tried:

- Repaired the game files, then fully reinstalled the game

- Ran the launcher as administrator

- Disabled Windows Firewall: no change

- Tested with another EA account on the same PC: same problem

- My brother plays Apex on PS5 on the same internet connection with no issues (so my network and EA servers appear fine)

The issue therefore seems to be tied to my PC and to Javelin.

My questions:

1. Is there a known issue with EA Javelin Anticheat since the September 29 migration?

2. Is my account or hardware under any restriction? I have received no notification and have never used any cheat software.

3. What do you recommend I do to fix this?

I have attached two screenshots (the anti-cheat error and the menu showing Squad 0/0).

Thank you in advance for your help.
