This line is going to be super helpful:

[11:28:23 ERROR]: Game ended with bad state (exit code -805306369)

This is printing what programmers call an exit code. An exit code is a value (usually an integer) that a program sends back to whatever started it when it has finished execution. Traditionally, 0 is a successful run, and anything else is an error, the values that are provided for the error are defined by the program, and are usually program specific depending on the type of error that occurs. Usually if you see a line like this, try googling the exit code in connection with the program the error is coming from (in this case, minecraft).

I haven't found anything online yet, but I'll keep looking.
