Thank you for sharing, and we're sorry to hear about your problems with the download.
What's it you're trying to download? Is that your project or a template? What's the format of the file that you tried downloading? Does it happen with every file? Are you seeing an error message?
Here are some workaround that might help:
Try editing from another browser, such as Microsoft Edge, Safari or Chrome
Test in incognito or privacy mode. Here are instructions for Chrome
Clearing the cache/cookies from the browser
Please send a picture or screen record if this persists so we can see what's happening.
