Description
At the end of downloading courses, this error shows up:
I think this error occurs when downloading exercise files because when I check the downloaded folder, the exercise file has 0 bytes size and when I want to open the file, it shows corrupted file error.
Can you please help me with that?
Operating System
[Windows 10 Version 22H2]
