Audio Units "couldn't be opened" in Logic

Hi!

I can't open any of the plug-ins that I have bought, which is KORG Triton and Roland Galaxy. When I go to plug-in manager in Logic Pro it says that they can't be successfully validated (se picture). First I tried to rescan and reset them in Logic. I have updated my Mac system (15.3.2) and Logic (11.1.2). No luck. I have tried to delete them from my computer and reinstall them. No luck. I have tried to move them from components file and then back in. It is always the same message and I don't know what to do?

Thank you

Hi,

Try a Full Reset.

1. Resetting Audio Units in Logic Pro:

Open Plug-in Manager: Go to Logic Pro > Settings (or Preferences) > Plug-In Manager.
Perform a Full Reset: Click "Full Audio Unit Reset"
Close and Reopen Logic Pro: Close Logic Pro completely and then reopen it.Logic Pro will rescan all installed Audio Units plugins
Check Plugin Availability: Verify if the plugins are now available in Logic Pro

2. Check for Compatibility: Ensure the AU plugins are compatible with your version of Logic Pro and macOS

3. Do the plug-ins require a license file? Check with plug-in manufacturer

4. Remove and Reinstall: If necessary, remove the AU plugins from your system and reinstall them

5. Restart Your Computer: A simple restart can sometimes resolve unexpected issues

6. Contact Plugin Manufacturer: If the problem persists, contact the plugin manufacturer for support

Hope this helps,
