STRAIGHT TO THE SOLUTION

01

Symptom

  1. You ready up, matchmaking cancels immediately and Party Not Ready appears. It often affects groups in which not everyone has the same game version or has completed the migration.
02

Step 1: update and restart

  1. Let the EA app or Steam fully install the current Apex update. Then close the game completely and relaunch it so the migration to Javelin completes on startup.
  2. Check: does matchmaking start when you queue alone? If so, the problem is within the group, not on your side.
03

Step 2: rebuild the party

  1. Leave the party, restart the game and invite your teammates again. Every member must also have updated and restarted once.
  2. Check: if the error only happens with one particular player, that player should repeat the steps.
04

Step 3: workaround through Steam

  1. During the switch, Respawn recommended launching through Steam if you had matchmaking problems. Apex is free; sign in to the Steam version with the same EA account so progress and purchases carry over.
  2. An early bug where Steam players lost their settings after every relaunch was fixed on October 2. This is a workaround, not a repair of your launcher.
05

Step 4: repair Javelin

  1. If the error persists, follow EA Help on installing and troubleshooting EA Javelin. Do not download anti-cheat files from other sources or try to bypass the anti-cheat.
  2. EA says Secure Boot is currently not required for Apex, unlike some other EA games. Do not change BIOS settings for this.

If nothing helps

  1. Note the time, platform, launcher and whether the error happens alone or only in a group. Report this to EA support; these details separate an account problem from an installation problem.

Frequently asked questions

Do I still need Easy Anti-Cheat for Apex?

No. Apex on PC has used EA Javelin Anticheat since September 29, 2026; the change arrives with the game update.

Will I lose progress if I switch to Steam?

No, as long as you sign in with the same EA account. Progress and purchases belong to the account, not the launcher.

Do I have to enable Secure Boot?

Not for Apex Legends. EA only lists Secure Boot as a requirement for other Javelin games.
