Garageband displaying error 100001 when loading up some AU plugins

I recently got some plugins from Universal Audio, and have licensed them properly through both UA and iLok manager. Whenever I try to load up the plugins (specifically from UA) in GarageBand, it first says that

"NSCreateObjectFileImageFromMemory-p47UEwps” because the developper can not be verified.

After clicking either 'show in finder' or 'okay', it opens the plugin in a form without its GUI and showing that it is not licensed (even though it is). It also displays error code 100001. I have tried only some basic stuff to troubleshoot like restarting the DAW/my computer and reinstalling/relicensing the softwares. I don't know if the macOS version has anything to do with it but for some reason I just can't get it to work.

Hello @omlecado19, thank you for your post. Are you unable to load a particular plug-in with GarageBand only, or is the issue present when you attempt to load it with other hosts? (You can build and run the Incorporating Audio Effects and Instruments sample code project, for example, and try to load your plug-in there to test.) If not, you should check with the support resources provided by Universal Audio to get assistance with their software.
