Hello PoCk3T, I hope you're doing well. I saw your post in the issue and was wondering if you could share how you resolved the problem. I am trying to understand this same issue in my own project and I believe your experience could be very helpful. Thank you so much for your time and collaboration.

Hey both, this issue could happen when there is a version mismatch between your node-template and the pallet. Try using the same version for both and rebuild after deleting the cargo.lock.

Thanks all for the feedback, I've indeed learned to remove cargo.lock and every other caches files as part of my development process
