I had updated visual studio to the latest version 15.9.7 and unity to the latest version 2018.3.4f1 and i click on the file i want to open on the window, and the file doesent open, the file loads partially and than the loading just randomly aborts itself after the “Hold On” window. Any help? thanks.
