Installed launcher on Ubuntu, won't start due to being unable to find blocklist-1.0.10.jar

Although I did try downloading mods before properly starting the game, the inability to use a non 1.21 version to bug test is itself a bug. Note that when I list computer paths, I will replace my computer name with [username], to maintain anonymity.

I believe the cause of this bug is that, when the Minecraft launcher was downloading, it did not create all necessary files. The file path specifically listed as nonexistent is

Path: /home/[username]/.minecraft/libraries/com/mojang/blocklist/1.0.10/blocklist-1.0.10.jar

The spot where this file path fails is within the /libraries folder (there is no /com file). I am concerned about how this incomplete download either made it to the public domain or was insufficiently bug tested with the Fabric system. Even though I am unable to find the current tutorial which I used to install Minecraft on Linux, I downloaded it from the official site before using the terminal to install dependencies. Below is the full error code I have been recieving, with the singular, aformentioned anonymity edit.
