'Python script when scheduled gives PermissionError: [WinError 5] Access is denied

I have .bat file which I want to run by task scheduler. Bat file has something like:

"C:\Python3\python.exe" "%PATH_to_script.py"

And when I try to run this from task scheduler I get this error:

PermissionError: [WinError 5] Access is denied

When I try to run the .bat file from file explorer by myself is working without any trouble.

Why is this happening and how to fix this problem?
