loading for minutes

yo guys i need help cuz since i reinstalled the game im always lookin at the loading screen for like 5 mins, but when i load in it isnt laggy or anything i got like 200 fps, so the problem isnt that my pc is too bad. another issue is that anytime i open the game it opens in windowed mode and in a weird resolution, and i dont understand why. i already tried reinstalling a few times, and repairing valorant through the riot client but it said theres nothin to repair. so if some could help i'd appreciate it
