Manually Installing QGIS missing dependencies

Hello. I’m having trouble installing the Speckle plugin for QGIS. I’ve attempted the solutions that you’ve previously posted, including following the video explaining how to install directly from the repository.

The message in QGIS is this:
Python error : Couldn’t load plugin ‘speckle-qgis’ due to an error when calling its classFactory() method See message log (Python Error) for more details.

And the Python error is this:
2024-04-16T23:55:42 CRITICAL Traceback (most recent call last):
File “C:\PROGRA~1/QGIS33~1.1/apps/qgis/./python\qgis\”, line 426, in startPlugin

raise Exception(m)
Exception: Failed to install dependenices through pip, got 3221225786 as return code.

Should I re-attempt or is there some new way of dealing with this which I’m not aware of?
