File is Processing
If the file uploaded is large in size then it will take some time for OneDrive to process the file. Especially in the case of a video file, it will take some time for Driv to process the video. You can either wait for some time and reload the page or directly download it.
File is Corrupt
If the file is broken or has some elements that break the code then it may not open in the drive. A corrupt file will not open in Drive, you need to download the file and check instead.
Disable Extensions
If you are using an extension on your browser then it may block the element to load. Browser extension scans the web page and checks if there is any action to perform. The extension scripts may block OneDrive to load the preview due to various factors involved or security reasons. If you have any extension that blocks/modifies scripts or codes, disable such extensions and check if the issue is fixed. To do so;
Type chrome://extensionsHere click on the extension toggle to Turn OFF.
Once done restart the browser and check if the video is loading.
Clear Cache on Browser
The cache is a small data stored by the browser for each website you visit that helps the browser to save user info, load pages faster, and keep the identity safe if you log in to any site for security reasons. Cache build-up can cause some websites to not load properly. Simply clear the browser cache to fix the issue. A filled cache can block the page load. You can simply clear the chrome cache and see if the issue is fixed.
Click on Chrome Settings
Now click on Privacy and Security of Sidebar Menu and click on the Clear browsing data option
A dialog box will pop up, here select Cached Images and Files, and click Clear data
Now try to preview the file and you will notice the issue is fixed.
