My minecraft Crashes on startup

When I start up my Minecraft, it either does not open or it opens, when it doesn't open nothing happens I go into the Minecraft launcher and it says its running. If it does start, it usually goes 3/4 of the way through loading and freezes, I have tried waiting and I sat there for 20 minutes and nothing happened. So usually I force quit it. My friend told me to uninstall and reinstall, I did that, still, the same thing happens, I even when I uninstalled I deleted the .minecraft folder. I don't know what is happening, please help

also to clarify I am on 1.14.4 and other versions don't work either
