Describe the bug
I cannot open an existing mapset or create a new one. The wxGUI crashes as soon as I press the "Start GRASS session" button.

To Reproduce
Steps to reproduce the behavior:

1. Start GRASS with the "-gui" option.
2. Select an existing location and mapset, or create a new one.
3. Press the "Start GRASS session" button
4. The wxGUI crashes with the following error:
   Launching GUI in the background, please wait...
   GRASS 7.8.5 (newLocation):~/Documents/Kelp > Traceback (most recent call last):
   File "/usr/lib64/grass78/gui/wxpython/wxgui.py", line 73, in OnInit

   self._textfont.SetPointSize(self._textsize)
   TypeError: Font.SetPointSize(): argument 1 has unexpected type 'float'
   OnInit returned false, exiting...

Expected behavior
Not to have a crash, naturally. :)
