Stuck in the loading screen. (Garena)

Greetings! So let me explain what's happening.

After champion select, the client will close and open you to the loading screen. When I'm at the loading screen, the percent bar is slow or even not moving. Usually, it starts at 4% then goes to 70% after a few minutes, it either crashes or closes because of remake match. Yesterday, it was totally fine. Btw, my internet speed, ping, download is totally fine and the specs of my desktop is compatible.

Please excuse my English. Thank you in advance!
