[BUG] A fatal error occurred while downloading the course.

[ehsanzalian]

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]
