This bug keeps occurring and i do not know why

OS: Windows 10
Problem: whenever I launch Minecraft, not sometimes always, it says:
[16:13:28 FATAL]: Fatal error launching game. Report this to http://bugs.mojang.com please!
Now I don't know if it's because my computer is bad or not (it is bad...)
but it says plz report so I did. I'm wondering if it has to do with how bad it runs.
for me... it needs to run smoother.
but anyway, I don't know what this is but I want to make sure it doesn't happen again
