Your system is probably using python 3.10. Pivy (the Python interface to Coin3D, the library that generates the scene graph) is not yet available for that version of Python.

i downgrade to python3.9 now iam getting this error

freecad: error while loading shared libraries: libpython3.10.so.1.0: cannot open shared object file: No such file or directory

[marioalexis]

This is because the version of FreeCAD you have installed (I suppose it was installed through the package manager) is linked to Python3.10.
To use Python3.9, the program must be linked to Python3.9.
So, or you compile the program again using Python3.9, or you can use an AppImage until the issue between pivy and Python3.10 is resolved.
