Portable 6.0.0: TypeError: QFont.setPixelSize()

[Kevin O'Leary]

Calibre Portable 6.0.0 upgrade
Windows 11

Get the following error when trying to launch:
calibre, version 6.0.0
ERROR: Startup error: There was an error during calibre startup. Parts of calibre may not function. Click "Show details" to learn more.

Traceback (most recent call last):
  File "calibre\gui2\main.py", line 315, in initialize_db_stage2
  File "calibre\gui2\main.py", line 258, in start_gui

TypeError: QFont.setPixelSize(): argument 1 has unexpected type 'float'

Main program then hangs and I have to use Task Manager to end task.
