This grabs the newest fltoken/caldera and also all other args
You can see the args I grabbed here
Make sure you left a backup with these files from the Win64 folder before you paste the files from this grabber in FortniteClient-Win64-Shipping_BE and FortniteClient-Win64-Shipping_EAC in
Now Replace your fortnite files with the arg grabber (not the one you put in the folder whats on step 1.)
Then launch fortnite from FortniteClient-Win64-Shipping.exe then it should give the fltoken in the console and files in args.txt
The FortniteClient-Win64-Shipping_BE and FortniteClient-Win64-Shipping_EAC are in FortniteGame\Binaries\Win64 if you can't find it
