Tcl issue --> _tkinter.TclError: Can't find a usable init.tc

[FredrikHj]

Hi

I am newby on Python not i programming :)

I am trying to start a Python project in VSC. I have Python 3.13.0 installed and the Python extension with Code
Runner in vsc. When running the GUI app with code:
import customtkinter

app = customtkinter.CTk()
app.mainloop()

Just to get up a Window frame. I get the fault:
"

This probably means that Tcl wasn't installed properly."
