Game becomes unresponsive on task manager on start

When I launch the game, screen becomes dark and then the logo pops up, after 5-6 minutes menu show up, background remains black for a while and then the character becomes visible and then when i try to join a match the loading screen takes like 15 minutes to get to 95% and then i lose connection, i have to eventually quit the game from task manager and force quit the pc with button if playing on fullscreen. I tried turning windows defender and firewall off but it doesnt work.
PC's specs are -
i5-4460S, 2.90GHz
AMD Radeon R7 M265 (2GB VRAM)
8GB Ram
Tried reinstalling and verifying game files.
[note: when i launched the game for the first time it took less than 1 minute to join a coop match and it ran fine, after running the game second time it started getting stuck at 95% and take alot of minutes.]
