Crashes on launcher

I just got minecraft 1.12 and it happens to me as well

It's the same thing for me
*Please Mojang, help us. There is no issue
Help*

Same here.
I tried to run 1.7 for a Map I'm been working on; however, it keeps crashing.

I added a screenshot

I just purchased Minecraft last night and downloaded and this exact same thing keeps happening. I have uninstalled and reinstalled and nothing is working. It's pretty disappointing that I paid for this game and I'm not even able to use it. Please let me know if any of you find a solution or if any of you know why this could be happening. Is there a problem on their end? Please someone help 😞

Thank you
