Additional Troubleshooting
In some cases, you will need to force Studio One to rescan all plugins at start-up. To do this you'll need to navigate to the following locations and delete the x64 or ARM64 folder:

Windows: C:\Users\<username>\AppData\Roaming\PreSonus\<Studio One version>\x64

This folder is hidden by default. Learn How To Show Hidden Folders

macOS (Intel): ~/Library/Application Support/PreSonus/<Studio One Version>/x64

macOS (Apple Silicon): ~/Library/Application Support/PreSonus/<Studio One Version>/ARM64

These locations are hidden by default. You will need to hold down the "Option" key on your keyboard within the Finder "Go" menu in order to access the User Library.

Note: This will clear your Studio One preferences and manually force Studio One to rescan all installed plugins.
