WinError 5: Access is denied when trying to write pdf with pylatex

Question

Code:

import pylatex as pl
#import latexmk

doc = pl.Document()
doc.append(pl.Math(data=['x^2+3x+1']))
path = r"C:/Users/maach/OneDrive/Documents/Python Scripts/mathfile"
doc.generate_pdf(clean_tex=False,compiler=r'C:/Users/maach/anaconda3/pkgs/latexmk-4.76-h57928b3_0\Scripts', filepath = path)

Spyder Kernel:

PermissionError: [WinError 5] Access is denied

Perl is installed in Anaconda environments. I've tried updating pip and running Spyder as administrator. Full permissions allowed on the folder containing latexmk and the target directory. Have not seen any other questions asked like this on any programming website. How do I fix this error?
