After installing 4.17, visual studio required to reinstall version that already existed. Could that be related to blueprint crashing issue? Suddently I cant open any blueprint or even make a new blueprint and open that without crash (issue in both 4.16.3 and 4.17). Suddently it might work. I could open references for some asset and then some blueprint. Suddently all blueprints worked again, and could load even a map normally. All worked then normally until restarting editor and the same mess again. Just changing again to use old backup. Probably will reinstall visual studio just in case if its somehow corrupted. Anyone else here with same problem? Something unknown tries to break my Project. Have verified engine versions and deleted saved/inter folders from project many times.
Edit: It wanted me to install VS2015 so seem like its not even meant to work with 4.16? Going to install that VS2017 again and follow these settings.
