I don't know where this function is supposed to be imported from but it is not in any of my Python 3.13 packages.

NameError: name 'open_browser_func' is not defined
Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib64/python3.13/tkinter/init.py", line 2068, in call
return self.func(*args)

btn = ttk.Button(info_frame, text=text, command=lambda url=url: open_browser_func(url), style="TButton")
^^^^^^^^^^^^^^^^^
