Hi jacubert,
i have got the same problem and I solved it the following:
I had moved one bfd library, so the path in bfd 3 was wrong. In my case this caused the described problem. Logic crashed on every start when bfd 3 was loaded as a plugin. Same Error massage like yours.
As soon as I removed the library. everything was fine.
To find out what library is affected, I rescanned the BFD 3 plugin in Logic. The rescan stuck in the middle and after shutting down Logic I found a warning on my desktop, telling me the path of the missing library.
Maybe this helps.
Best Regards
