Example download progress randomly gets stuck in 0%

Sometimes example download does not progress, but gets stuck in 0%. Reproduces in RTA tests rounds randomly, to any of the examples. I've also encountered the issue couple of times, when testing manually.

Might need multiple attempts to get the issue, but these steps can be tried:

• Delete existing examples (<user>Documents\QtDesignStudio\examples). I've also deleted cache (<user>AppData\Local\QtProject\QtDesignStudio\cache) but not sure if that's relevant
• Start downloading examples one by one
• -> Some of those downloads might get stuck in 0% progress.
• -> Canceling download and starting it again solves the issue.
