Launcher does not run after update

I ran Minecraft. It finished the Launcher update

When I click play, after waiting for it to connect, it keeps saying download failed, yet I do have internet and can browse to different sites. The error reads: Failed to download file.
Name: realms-1.14.17.jar
URL: https://libraries.minecraft.net/com/mojang/realms/1.14.17/realms-1.14.17.jar

It seems to  keep getting stuck on 18.02 Mb downloaded
