Though not really a bug IN Minecraft, it might be a bug causing me to crash.
I made a previous report on this, but this one adds more to what might be the problem. I've searched everywhere for an answer to the crashes, I also get this error code when it crashes from the launcher log, but never found anything from it:

Process crashed with exit code -805306369
The logs show nothing important, no reason for crash, not even anything failing to load.
There are also No Crash Reports

If you could explain the crash code above, that would be great. Cause I'm running out of options at this point. I've re-installed every file, and updated everything I can. I just don't know what there is to do other than ask you for help.

Also whenever it crashes, I can open Task Manager and force close the Launcher which opens the game... And if it opens the game and doesn't crash, launcher is still opened (according to task manager) and I have that option off (to keep launcher opened) when I enter a world, it crashes. But by closing the launcher with Task Man, it joins the world... Idk why this happens.

Also skins and all that are still default.
