[MCL-21046] Vanilla Launcher no Longer Works

When I use the vanilla launcher on any version, this pops up:

Failed to download file.
Name: 1.18.json
URL: https://launchermeta.mojang.com/v1/packages/6b87c76d1edcb1fb0d933382cbb8bb8483c362c4/1.18.json
Error details: HTTP server doesn't seem to support byte ranges. Cannot resume.

I've been using launchers like Lunar Client and Cheatbreaker right now but can't use the vanilla launcher. How do I fix this?
