I can give you more specific steps once I know the scale of the mod you're working with!
If you are installing a "Remastered" graphics mod or a "Real Cars" pack, you are likely dealing with an OIV file over 2GB.

OpenIV is the backbone of the GTA V modding community, but the "Package Installer" stage can often feel like it’s stuck in a permanent loop. When you are staring at a progress bar that hasn't moved in ten minutes while trying to install a massive OIV file, it’s usually due to file size, disk speed, or administrative permission conflicts.
OpenIV always asks if you want to install to the "mods" folder or the "game" folder. If your "mods" folder is on a different drive or if the pathing is complex, the installer may hang while trying to calculate the available space and write permissions. 3. Windows Defender Interference
