Steps to reproduce

I dont exactly know how the consistent crashing came to be. Before it was all good when i played and tried reinstalling and installing and still gives me the same crash. Checked my java versions but all are good and nothing was wrong.

Suspected cause

My guess would be the sudden closure of the launcher. Not that sure
