Launcher would launch the game but to crash soon after. Help!

Hello, call me Two Five.

The last time I opened and launched Minecraft was somewhat 2-4 months ago (I believe). It worked and so I played about a week's worth no problem.

I decided I wanted to start playing Minecraft again after watching Pewdiepie's Minecraft Let's Play as it would sound like fun to get back into the nostalgia again. But it was only 3 days ago (date 17.7.19 ) that when I wanted to play again, Minecraft would launch but immediately crash. 

The email connected to my Minecraft account is different from this "Jira" account. I recovered the details of the Minecraft account through Minecraft.net but still, the Minecraft game would continue to crash. Furthermore, I could not review the crash report.

The only thing that comes to mind is that the account is accessed on a different device. This device would be my older brother's as I lent him the login details and play my account. But right now he has stopped playing Minecraft.

Please help, I want to create a hardcore mode world and have fun.
