Several Launcher Errors

It is the second time I'm opening a thread in this forum about this. The last time was months ago with the same issues and the only thing that worked was restarting the launcher countless of times until it downloaded the game and installed everything. Not to mention that after that time every single patch would give me errors like these.

I just did a fresh windows reinstall and when I try to download the game I get different errors like these:
A problem occurred while updating [11006] [20641] [20643]

Unable to download patch files [30413] [25008] [20495] [20495]

Unable to complete version update [30437] (launcher crashes with this one making it completely unresponsive)

I've tried EVERYTHING I could find on the internet, even the copy pasted "solution" the mods here give, like this one:

Good afternoon and thank you for posting in the Final Fantasy XIV Technical Support Forums,

We apologize for the delay in our response, please try the following troubleshooting steps:

- The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Right-Click on the FFXIV launcher icon and select "Properties"
- Hit "Apply", then "OK" to save the changes.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

I also tried changing the DNS to google, tried deleting the patch folders from My Documents, tried using VPN (Exitlag). I'm connected through ethernet cable as it is a PC and does not have Wi-fi.

I honestly don't understand why it's so difficult to install a game. This only happens with FFXIV and no other game.

UPDATE: someone on reddit mentioned something about the documents folder having to be the same language as the installer. So for reference my OS is in german and the launcher was installed in english. I uninstalled the launcher and deleted everything related to ffxiv in my Documents folder, installed the launcher again but this time selecting everything to be in german. By doing that the launcher manages to make progress but still getting lots of errors and I still have to delete or rename the patch folders in Documents.

THIS IS NOT A FIX! But if someone finds this post on google it's worth a try if it's relevant for you
