Strange Crash Due to Error From Missing Class: net.minecraft.client.gui.screens.LoadingOverlay (Minecraft, Forge, 1.20.1)

[Benjaggo]

I have been trying to solve a consistent crashing issue on my brother's computer where it will crash during the "Scanning Mod Candidates" phase of the loading process that starts when you click the play button on the Minecraft launcher.

The issue seems to stem from a missing library that it mentions in the log file I provide below. I might I'm missing the bigger issue here for a smaller one but hopefully someone can find what I'm missing.

Here's all of the stuff that I've been able to figure out so far:

1. It has nothing to do with mods, the crash happened with a real modpack, and even when I made a custom modpack and launched it without putting ANY mods into it (That is where the log file comes from by the way).

2. I have tried to find this class like a file in the Minecraft folders, but I've had no luck finding it (I don't think it works like that, but since I really don't understand how it works, I just figured I'd try).

3. I haven't seen anyone else have this issue before.

4. I know that my modpack (with mods) does work since I've run it on my computer, and it works fantastic. For some reason my brother's computer can't seem to run anything through curseforge.

5. This is for Minecraft version 1.20.1, Minecraft launcher version 3.4.50-2.1.3, forge 47.3.0, and curseforge app version 1.256.0.21056

6. My brother is using a Dell laptop from 6 years ago running Windows 10 (If you think more info on this would help, please ask as I do have it. I'm just choosing not to put it here for now).

7. I have reinstalled the curseforge app and installed Minecraft version 1.20.1. I have not reinstalled Minecraft or forge 47.3.0 but I didn't know if that would help.

8. I had an error code of 1

Please let me know if there is anything else that I am missing that you would like me to add to this post/add in a comment!

Lastly, many thanks in advance to whoever can help!

------------- LOG FILE (latest.log) -------------

(This was made after running an empty modpack with same versions for all apps)

But does this name contain special characters or spaces?

No, every one of the [REDACTED]'s represent a single word, like a name, or a user ID. For special characters, none of the [REDACTED]'s had any special characters in them. So, in reality, they were all a single entity (string of regular characters, or numbers). Some examples: "1234567abcdefg" or "aNameOfaPerson52".

Same issue with another Launcher like MultiMC or AT Launcher?

I haven't tried any other launcher.

I think I'll go and try MultiMC, and if the same error happens, we'll know that the problem doesn't stem from the launcher.

I'll reply here after I try that!
