How to make Apex Legends WORK (if you're game is not starting up)

Try to delete this folder C:\Users\YourName\Saved Games\Respawn

this will delete local save save which can causing profile loading  issue

Make sure that this folder is not set to READONLY when it recreate after game relaunch

add "-quickstart" command [without " "] in game properties [Origin -> Click on Apex in your game library and then rack icon]

That operation helped me bing back to the game

Cheers

EDIT:

Sorry , I wrote incomplete sentence ,so

you should try to delete this folder first [C:\Users\YourName\Saved Games\Respawn],then launch game and  then  uncheck Read Only [folders will recreate after game relaunch --> just launch game one more time]

If it doesn't work then You should try Repair the game in Origin , run as Administrator or add "-quickstart" command [without " "] in game properties [Origin -> Click on Apex in your game library and then rack icon]

First i deleted that folder C:\Users\YourName\Saved Games\Respawn

then i added that -quickstart command in game properties then I launched game and then i unchecked Read Only in recreated folder properties [it will change back to read only itself ,so I just leaved these tabs open on desktop [ Respawn & Apex & local ]with unchecked Read Only ]

That's it , It worked for me when i launched the game second time , because at the first time it get stuck at black screen with that red Gif thing in right down corner
