[BUG] [OSError: [WinError 87] The parameter is incorrect]

[anchit-h]

Context

• OS: Windows 10
• Install method: Manual. Unzipped the folder and ran all commands one by one. Installed Python 3.7 (uninstalled other versions)
• Your location: Outside the campus
• Course URL: https://a.impartus.com/ilc/#/course/1374617/706
• Lecture range: Tried blank, 1:3, 1. Also tried the second option "only_new" radio button.

Additional context
I've tried several combinations of input (like changing video quality / both-left-right / different correct ranges). I've also tried running from the command line as well which leads to the same bug.

In the logs I went to downloader.py and I'm printing out cmd and sp_args just before line# 187. If you need any further information please let me know.

Describe the bug

1. On the cmd prompt (runnning with /without admin privileges : poetry run python ilc_scrape.py
2. The GUI pops up
3. Enter the course URL https://a.impartus.com/ilc/#/course/1374617/706
4. credentials are put into the imp_config.json
5. Click start
