Hey, I had same issue.
Found a post mentioning it might have something to do with my connection. The solution they suggested, was to get a VPN.
I downloaded one (Windscribe), used a trial version to test it. All crashes gone after that, but the VPN gave me bad lag, because the trial version had limited servers to choose from. Noticed humblebundle.com had a sale where you get 1 year premium for 12$ (Sale is up for 6 more hours) and now I got no lag and no crashes
Used to crash every 10-15 mins. I’m also speaking with the support atm., seeing if there’s something they can do, so I don’t have to use and pay for a VPN.
