Could Fortnite be over 150 epic friends?

I don't have that many friends on another account and it doesn't lie either. Ps there are different Windos accounts but on the same PC.

Possibly, a setting has been made in one of the "lagging" accounts, which may bring the game to a standstill.

It's not because of the friends.

See Youtuber who have 1000 friends, there's nothing with them

It may also be that your PC is no longer interested in Fortnite (but is also understandable)

Actually not when lying with friends has to do only because you have too many friend requests

Friends list runs on the server side, so not the problem.

Maybe the problem can be solved by deleting fortnite?
