Description of your issue, suggested solution and other information

I tried to download the course here:

https://www.lynda.com/Illustrator-tutorials/Illustrator-CC-2019-One-One-Fundamentals-Revision/784289-2.html

Using a cookie.txt file, using powershell in admin mode, on windows 10 latest update, and at the end it gives me an error about JSONDecoding, As in the log above, and does not continue past that.

It is a library login method with a downloaded cookie.txt using the chrome extension.

Apparently if I remove the --write-subs it downloads without issues.

However no subtitles are downloaded
