"The filename, directory name, or volume label syntax is incorrect."

Tribler 8.0.7, when Windows OS reports the error (ERROR_INVALID_NAME, 123 (0x7B)) message, "The filename, directory name, or volume label syntax is incorrect.", Tribler simply... stops the download. There is no message or error reported in WebGUI.

System errors like this should be reported so it is easier to interpret why Tribler stopped.

I can create a similar type of situation in Ubuntu:

1. Start a download, set the location to some removable medium: I used a USB stick.
2. Exit Tribler
3. Remove the USB stick.
4. Restart Tribler. The download will just sit there on "Downloading 0%" and not do anything.

The logs have this message:

We need to think of a way to communicate to the user that the download is "broken".
