Also add what you already tried so far.
Reinstall FiveM without delete files add in the folder of the game (If new files are created when we install FiveM)
Try to use your email address instead of your login name. That’s how I fixed it on my side.
I use only my email adress
Okay, I delete the file “caches”, desactive my antivirus in the same time and it work
so do you use your email adress or your user name after you delete the caches file to login
also i am on windows 7
