New Minecraft launcher crashs when I open it

I updated to the new launcher and I played on it, after that I uninstalled the old launcher and when I opened the new one I only could play the demo. I tried to uninstall the launcher and install it again. But now when I try to open the new launcher it appear an error message that says that the data is corrupt and that maybe if I reinstall the launcher the problem will solve, but I tried it and don't work.

I installed the old launcher and it works correctly, but help me please
