The infinite loading circle — at the title screen, entering the lobby, or dropping into a match — means the client is waiting on something that never arrives: a service response, a party sync, or an asset load. It's a symptom with several distinct causes rather than one error, so the fix is a quick process of elimination.
If the game loaded fine yesterday and hangs today, check Apex server status first. A loading screen that never resolves during an EA incident is their problem, and the only fix is waiting.
Close Apex completely and relaunch. If you were in a party, have everyone leave and re-form after restarting — a desynced party session is a classic infinite-load trigger at match start.
On Steam: Verify integrity of game files; on the EA app: Repair; on console: check storage and re-download any add-ons that show as corrupted. Damaged assets stall loading at the same spot every time.
Make sure the install drive has free space and is healthy. A disk struggling to read assets produces exactly this hang — moving the install to a healthier (ideally solid-state) drive fixes the chronic version of it.
From the lobby, pick a different datacenter and retry. If loads hang only at match start, sustained packet loss to one datacenter is a likely cause — a wired connection and a router restart address the local half of that.
Either the servers are struggling, your session/party is desynced, or the client can't finish loading assets — usually corrupted files or a slow drive. Restart and re-form the party first, then verify files, then look at the drive and connection.
Match-start hangs point at the connection to the assigned datacenter or a party desync, not your install. Re-form the party, manually select a healthy datacenter, and check for packet loss.
