Game wont load completely after launch.

this happens to me I have not found found a way to fix this yet except for closing the launchers task in task manager after I launch the game though this only fixed the problem for that session. after I launch the game Minecraft itself under java(TM) platform SE binary uses 60 percent of my CPU until my computer auto stops it making it not respond and then the game doesn't load until I end the launchers task. I have reinstalled the launcher many times, I have even reinstalled java and tried both 32 and 64 bit to see if it worked. The attached images show task manager as soon as I launch the game and the crash report the launcher gives me.https://paste.ubuntu.com/p/q99jkPhpZr/ This is the link to the log after the game has crashed.
