Unable to update the Minecraft native launcher

So, a couple weeks ago I was playing minecraft just fine. I opened it one day after already having played it prior, and it says "error 1.14.1.jar" or something like that. After meddling with it a while, it now says "unable to update the minecraft native launcher." ive searched and tried to fix it on my own. Im open to trying things again but I've already tried: minecraft.exe download and reinstalling it after uninstalling it. Ive also tried repairing it but ill try again if need be. Please help
