Big Sur update missing IOKit library

I have a program I have developed with XCode and used for ALL version of 10.x.x - worked fine. After updating to Big Sur it longer runs. The error I get is:

dyld: Library not loaded: /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit

What do I do about that ?
