Since yesterday I am encountering game crash every so often it is impossible to play a game. For particular game I can just start it, wander around for a few minutes without interacting with anything and crash happens.

Below is the content of crash report as provided by minecraft itself. I can provide save, if necessary, the current size is 2.2GB uncompressed/1.5GB compressed.
