Self explanatory in title.
It should be noted that there is no precursor to such crashes before they happen. The window simply automatically closes itself and the launcher pops up. No other windows appear.
Additionally, the following text will appear in the launcher's window:

It should be noted that these crashes to not seem to happen regularly. They may occur any time from a few minutes to a few hours after starting up, but always while online. I have not tested for this bug in Realms or Singleplayer.
Attached are a few error logs that are generated each time the program crashes. The expected *.txt files do not appear to be generating.
