Hi @SimoneColomboWEG ,
Thank you so much for your interest in our products and for using our community.
Regarding your question, I suggest you carefully check the following points:
1: MCUXPresso IDE version and SDK lib version should be compatible.

2: Have you checked for differences in the Project -> Properties -> C/C++ Build settings between the two projects?

3: Have you tried running an SDK demo on your PC?
Wish it helps you.
If you still have question about it, please kindly let me know.
Best Regards
MayLiu
