XIVLauncher gives same error (One or more errors occurred) no matter the login every time FFXIV is launched

Update disclaimer

• Yes, I have checked and my issue is not related to the game updating and plugins not working correctly.

What did you do?

I installed XIVLauncher for the first time and set my directory to the free trial installation I have of the game for my alt character for fresh progression and playing with other friends newly starting purposes, I chose to install Dalamud with XIVLauncher, and when I put in my user information I get a popup saying "XIVLauncher could not save your account information. This is likely caused by having too many saved accounts in the Windows Credential Manager." but then after saying OK to that one since that's just login ease of access, I then get the error "Unexpected error has occurred. (One or more errors occurred.) Please report this error." Also asked around the XIVLauncher discord and other people couldn't find a solution either, so what's the solution?
