Wanted to update and say that I found the (somewhat unexpected) issue! Unsure if it’s an issue with my personal laptop or a more general issue, but it seems that Fortnite will keep a background process of Easy Anti-Cheat running even after the game is closed. I have to manually end the background process through task manager regardless of how the game is closed. Was able to get it running and incredibly happy with the results. Thank you for your help!
