For the past month or so, my minecraft launcher will sometimes refuse to start up. The launcher will behave, at first, as though about to load, and a grey window will open, but this window will only close and the launcher will seemingly crash. Once this occurs, the launcher will not open until the computer is completely restarted, whereafter it may or may not open up normally (there seems to be no consistency on whether restarting does or does not work, but it is necessary once the crashing begins). This strange crashing behavior can begin anytime the launcher is closed, both when the window is closed by the red x on the corner or if closed through task manager. Even when the launcher can be reopened after closing it, this does not seem to guarantee that it will reopen if the launcher is closed again, and I can find no pattern in what triggers this crashing. To be clear, this is the launcher crashing and not the actual game. Hopefully this is just a problem I am experiencing, but if it isn't, hopefully this helps
