Client freezes at loading screen

Each match today, my client proceeds as normal until the loading screen.

The game loads to 100%, then my ping drops from 100~ down to 70~ and I cannot load into the game.

I'm forced to wait 10+ minutes until my team remakes or close the entire client and reopen it, and then hope I can load in before I'm too far behind.

From what I've read this has been going on for some time?
