Error in compiling New Matplotlib V3.4.1 release

[xo-HADES-xo]

Description of the issue

• Prior versions of Matplotlib (e.g. 3.3.4) compiled correctly with no issues
• With new release (3.4.1); there is an issues where Pyinstaller does not create the correct data in "myProgram\matplotlib\mpl-data" folder
• Instead, Pyinstaller copies the whole directory where source code is located + the all the source code to the "mpl-data" folder

Context information (for bug reports)

• Output of pyinstaller --version: 4.2
• Version of Python: 3.8.8
• Platform: Windows 10 (English)
• Did you also try this on another platform? Does it work there? Only tried on W10

Can you try using develop branch? This looks like a duplicate of #5567, and should already be fixed by #5568.

Yes, thanks.
switching to public get_data_path in matplotlib hook worked. Did not see previous message
