Game doesnt turn on

[Reubr]

My problem started today (have played for few days and everything was fine, even 15 hours ago)

I was looking for soloutions, trying some of them all (with waiting for 20 minutes to start after doing any of them), but nothing happens :( (tried system restore, uninstalling whole game)

Additionaly, when i launch game nie, my system is lagging top, cant open task menager od run anything
