Resource Packs page is extremely slow to load

Ever since 1.20.2 when you click on Resource Packs page, the game can easily freeze and load the page for a minute or so. It depends sometimes it takes only few seconds, but after a moment dozens of seconds again. Even if it takes less than few seconds, before 1.20.2 it was instantaneous!
I have many folders inside resourcepacks folder, around 50 resource packs folders/zips and another nested folders. I have minecraft saved on HDD. All these are propably the factors slowing down the loading, but as I said, the loading worked instantaneously in previous versions. So why not in 1.20.2 and above?
I think the main reason is that you can't have many resource packs in a folder inside the resourcepacks directory of the game like before, else you experience the game lagging every time you open or the game loads things regarding resource packs. In older versions that was no issue, but now the game does some unnecessary loadings of things that aren't resourcepacks it seems.

Overlays
It is as if the game tried to get through every folder and file there is instead of just picking on the main aspects like picture and pack.mcmeta. As I thought about it, I also assume the issue is related to new overlay system in packs, because the game must now recognise more "sub-packs" in the resource pack itself. The issue is that it seems like it is checking for things it doesn't even need to, because it really just needs to really know the content of almost only one file that is directly in the first folder and that is pack.mcmeta, not every other folder.

In the logs it gets stuck on lines like:

[18:09:02] [Render thread/INFO]: Found non-pack entry 'D:\Users\DelimanCZ\AppData\Roaming\.minecraft\resourcepacks\#archiv', ignoring
[18:09:55] [Render thread/INFO]: Found non-pack entry 'D:\Users\DelimanCZ\AppData\Roaming\.minecraft\resourcepacks\#versions', ignoring

I was working with resource packs in the past, so it is very convinient to have sorted folders with resource packs inside the resourcepacks directory. I will include some folders in here so you can try yourself (extract this to your resourcepacks directory): https://drive.google.com/file/d/1gESaV3yavJ5dtbC9YNmkRQX6nh59xhH3/view?usp=sharing

Do you have any resourcepacks in %appdata%/.minecraft/resourcepacks ? If so please try removing these and see if it speeds up loading time
Please attach the full launcher log found in [minecraft/launcher_log.txt|https://minecrafthopper.net/help/finding-minecraft-data-folder/].

Thanks for attaching the log and updated description.

I can see some errors relating to resourcepacks in the log file, such as

Unable to load font 'minecraft:pre1.20/default' in fonts.json in resourcepack: 'file/Back to Minecraft 1.8'

please try removing that resourcepack, and all resourcepacks, to see if that speeds up loading

Of course if I remove all the resource packs it runs quicker, but that's the issue.
It's not by some error, if I remove the pack with error, it is no change.
If I have more resource packs it just lags the game when loading it and that's something that is not happening in versions before they changed something about loading that page.

I cannot reproduce this. My 5-year-old PC with way too many resource packs at once loads the resource pack screen instantly.

Please see if community support can help solve this issue

Closing this is invalid as multiple people cannot reproduce this issue and my guess would be that it has more to do with your PC than the game itself.

@Greymagic27 @zTxrbq Look, I don't know how else more clearly can I describe it to you. I tested this on multiple computers now and it is VALID. They did something with the loading algorithms of the packs that just made this 1000x slower, similarly like it happend to singleplayer worlds load some time ago. It is very good to have your .minecraft folder on hard disk (HDD), so you can clearly see the issue. I tested it on multilple computers with 4 year old and diferent HDDs. Just download the file I have, extract it because those are folders of packs I have inside resourcepacks folder, and run the game from the launcher to see just how long it takes to start because of the resource packs. You can then click on Resource Packs in the game and SEE THE FREEZE AGAIN AND AGAIN, almost every time you open it.

I'll reopen this but I still don't believe this is a game issue, but a PC one instead.

@Greymagic27 Yeah, when you have quick SSD it's not as noticeable as on slower mediums, but that doesn't change the fact that it's a performance issue that was not occuring before and can be sometimes quite significant.
