Why does my python task not run with windows task scheduler but it runs fine in the IDE?

Question

This is the code in question. I have the task running with higher permissions so it should not be a permission issue. It has the sole purpose of deleting files older than a certain date automatically and above a specific size. I was wondering why it doesn't run when either scheduled or opened manually with admin permissions. It does open but closes with no prints nor deletes any files it should have if it worked. I also have already tried installing the libraries on path which didn't work either.

import datetime
from dateutil.relativedelta import relativedelta


def Setup():
    Directories = open("Directories.txt", "r")
    dir = Directories.readline().rstrip()
    Directories.close()

    FSFile = open("FileSizeMax.txt", "r")
    FileSizeMax = FSFile.readline().rstrip()
    FSFile.close()

    Exclusions = open("Exclusions.txt", "r")
    ExclusionList = [line.rstrip() for line in Exclusions]
    Exclusions.close()

    lastDate = datetime.datetime.now() - relativedelta(weeks=1)
    formattedDate = lastDate.strftime("%m/%d/%Y")
    return dir, FileSizeMax, ExclusionList, formattedDate


# Get clips in directory
def getFiles(dirs):
    list = []
    list = os.listdir(dirs)
    return list


# Delete any clips older than the last date and larger than the MB set in the FileSizeMax.txt. Exclude any thing set in exclusions file.
def delFiles(files, FileSizeMax, ExclusionList, dirs, lastdate):
    print(files)
    lDate = datetime.datetime.strptime(lastdate, "%m/%d/%Y")
    for file in files:
        print(file)
        path = os.path.join(dirs, file)
        print(path)
        timecreated = os.path.getctime(path)
        size = os.path.getsize(path) >> 20
        date = datetime.datetime.fromtimestamp(timecreated).strftime("%m/%d/%Y")
        parseddate = datetime.datetime.strptime(date, "%m/%d/%Y")
        print(f'{file} created on {date} and is {size} MB\n')
        if date not in ExclusionList and size > FileSizeMax and parseddate <= lDate:
            print(f"Delete {file} {date} {size} MB")
            os.remove(path)


dirList, FileSizeMax, ExclusionList, lastmonth = Setup()
print(dir)
print(FileSizeMax)
print(ExclusionList)
maxFile = int(FileSizeMax)
files = getFiles(dirList)
delFiles(files, maxFile, ExclusionList, dirList, lastmonth)

I didn't realize dateutil was named python-dateutil when installing it so I just didn't have the library installed causing it to except. It works fine now. Minor mistake. Fixed it all by installing all of the relevant libraries.
