Adobe Media Encoder - Unable to load third-party audio plug-ins (default)

Hi. I’ve been using Premiere and Media Encoder with no issues, but now I’m having problems with Media Encoder (v26.5.2 Build 2) failing to load audio plug-ins. I uninstalled this version and installed earlier versions but I’m still having the same problem. I’m using Premiere (v26.5.2 Build 5), on a MacBook M4 Pro running Tahoe 26.6.2.

I have checked/changed the privacy settings as per info I can find/steps to follow (allowing access to Documents Folder & Removable Volumes), and I’ve uninstalled and reinstalled Media Encoder, but it hasn't helped. The plug-ins are working fine in Premiere.

Please assist.
