Crash/freeze when going to new map and ingame since latest patch

Hi,

I have been experiencing freezing/Crash when going to new a new map from previous match, and a freeze ingame since latest patch.

Also happened to a friend in competetive but for me it has never crashed the last 4 months, since new patch 4 crashes in a day

i7 6700k and gtx 1080 win10 64bit

EDIT
it seems like the hanzo might have something to do with it, always happen with new hanzo ingame.

Transitioning to another game from lost/won game happened the most, or the same to new round. Game freezes, sometimes can see the OW logo still moving.

A friend in party also had a freeze, similar to mine in same group later

Also having some issues, crashed once in a comp game during placements. found a match but stuck in main menu with option to reconnect. but couldn’t. restarted pc but still couldn’t connect, got a loss as a result. Hardware: i5 6600K oc to 4.5 16gb ddr4 gtx 1080ti. playing on 1440p 144hz
