Oh, we should only remove serial numbers when we are posting
config.plist to this or any other website so that no one "steals" your serial numbers. But serial numbers must be present is the working version of config.plist.
Based on the following post earlier today...
...it seems Logic Pro was working when it was initially installed (before any plugins were installed)?
The Big Question:
- Did you make a full bootable backup right after installing macOS and/or before installing the Plugins?
- If so, don't modify that backup disk in any way. Instead, clone it to a cheap spare SSD and boot from that spare SSD. Install only Logic Pro and check if it's stable. If so, install only one plugin at a time and check whether Logic Pro starts up normally.
If you don't have a backup of the system
prior to installation of Logic Pro or the plugins, then it might be a good idea to quickly perform a fresh installation of macOS on a spare low-cost SSD. Then install only Logic Pro by itself to check whether it starts up normally.
This might seem like a brute force method, but it may lead to some answers more quickly than other methods. Feel free to ask for help at any stage of this.
