AU validation error in Logic

Logic is very peculiar with its validation requirements. A user reported, that the regular version of our plugin is loading, but the PRO version is not validated. This issue was not present in the initial version of the plugin, but is present since we have changed the audio input to use the sidechain input.

FATAL ERROR: Initialize: result: -10875
validation result: couldn’t be opened

Apparently this tool helped fix the issue:

However, we haven’t tried this ourselves yet and can’t vouch for the integrity of the software provided by Mactech Audio (see YouTube description) , please proceed at your own risk until we further investigated the issue.
