[CRASH] Client crashes after accepting ARAM game (before champ select)

Hi,

Since a few days my client freezes (and crashes) after I accept the ARAM pop-up (right before champion select screen). The only thing I can do is closing the client with task manager and then re-start it. Usually I can instantly reconnect (game started even though my client was closed), but sometimes the game was dodged by me, which means I get a dodge penalty. This issue has been occurring for the past week in about 8 out of 10 games and it's quite annoying because I can't reroll, change masteries, runes or summoner spells OR I get a penalty for dodging. This only occurs in ARAM, in normals/ranked everything is fine. I recently updated to Windows 10 but that was around the same time of the latest patch, so I'm not sure if one of these might cause this problem. I already tried repairing the client which didn't solve the problem.

Extra info: **• Server: **EUW • Steps to reproduce:

1. Queue up for ARAM
2. Accept game
3. Client freezes and doesn't respond anymore • Expected result: Receive champion select screen after accepting • Observed result: Client freezes and crashes after accepting • Reproduction rate: 8/10 **• Operating system: ** Windows 10 **• LOL version: ** 5.15

I hope you can help me out with me with this problem.

Thanks in advance, I Like Swimming
