Minecraft crashes with exit code -805306369
Solution 1:
A quick Google search shows that the error code -805306369 means that the Java Virtual Machine has run out of memory. To fix it, you need to allocate more ram to Minecraft.
Presuming you are using the official launcher, you can do this by selecting a profile, clicking 'Edit Profile' and increasing the -Xms (minimum ram) and -Xmx (maximum ram), by ticking the 'JVM Arguments' at the bottom.
Example arguments would be: -Xms1G -Xmx2G = Minimum of 1GB RAM, maximum of 2GB.
