Minecraft launcher buggt?

I can't change my version in minecraft launcher, how do I fix it?

What happens? And what exactly is not possible?

As you can see in the picture, I can't choose a version. The area where else is possible is completely empty

Have you ever clicked on it?

I'm not that stupid xD

Then delete the profile. And create a new one. Try to change the version there. By profile I don't mean your Minecraft profile!

Yeah… I've already tried that…

Uninstall and reinstall Minecraft.

I had times you have to select the hack full version

Vlt you download a version of Minecraft e.g. 1.15 and insert it in% appdata% -> .minecraft -> versions then it could work again.
