Hi @vpfitofficial20
Welcome to the Shopify Community. Thanks for taking the time to reach out about this, and for updating the thread while testing other browsers.
We did experience a live issue with the Files section of the admin earlier today (around the time of your posting) and this issue has since been resolved. Are you able to please try clearing your cookies and cache on your Chrome browser and try uploading a file again? Thanks for your patience today while our developers worked on a solution.
So you know, I've just tried uploading a file to the Files section of my test store using Chrome, and it was successful. Make sure your browser is also up to date if you're still experiencing issues.
Let me know how this goes!
