the screen goes red

hello I have a problem.
A few months ago I bought a new computer and installed minecraft, when I wanted to play the game logo appeared, followed by the red screen and there it stayed, it does not advance anymore.
I asked for help but they told me to wait for the new update, today the update is already there but my game still does not work. I no longer know if it is a problem with my PC or what is happening.
Please I need help
