Crashes after changing instancesU

Saga of blood seems to crash when I leave a zone. White Sands to Tortage and Destiny quests at night. Additional continues to crash, after 3 times I chose to run “check for corrupt files” and it is incredibly slow. Even though it says “do not close the patcher” should I close it and try again? My game time is limited and this is frustrating during Saga of Blood. Hour later and the game won’t even load now. UPDATE after 2 full system restarts, finally back in the game. UPDATE. Crash in mini game too

I get the same every 9 times out of 10
