Why would this be???

The problem of core is not related to Blender 5. 1. Close Blender 2. Manually copy the library to the path with addon

I did that. It still doesnt work.

That's another kind of issue. You initially asked about CLib

Yes, and I posted here. Then realised I could copy it in manually. Now I have another issue.

Update ZenUV 3 from market, we checked and corrected everything for Blender 5.0
