Arch Linux KDE GDlauncher Not Working

When I try to install Mods on GDLauncher, it sometimes stays at 0%. It will not change after left for about 20 minutes. I am using an unofficial bin launcher since that is the only way I can do it. I have tried closing and reopening. I also prefer not getting an answer about uninstalling and reinstalling the app since I do not remember the password. Here is a provided image for reference. If there is anything wrong with my question please tell me so I can fix it. Thanks.
