Computer restarts upon saving and exiting Singleplayer Worlds

For the past week whenever I exit my singleplayer worlds on 1.16.4 and 1.16.5, my computer will restart. I'm not sure what could be causing this issue. I have tried many things including;

• Updating my graphics drivers and Windows OS
• Reinstalling the Version
• Reinstalling Minecraft entirely

The problem persists in newly generated worlds and ones generated in 1.14. It does not seem to be related to play time or where I am located in any given world.
