We can perform some troubleshooting steps to get the Apps tab working, Aliciawong.

You might be experiencing some browser issues. The system occasionally behaves strangely when the browser frequently accesses pages that could be due to corrupted cache files.

To rectify this, let's perform a few troubleshooting solutions. I suggest using a different browser or a private window. Depending on the browser you're using, you can use these keyboard shortcuts: 

• Ctrl+ Shift + N for Google Chrome
• Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge
• Command + Shift + N for Safari

Once done, go back to the Apps tab on the left navigation bar again. If it works, go back to your regular browser and clear its cache to start fresh. Also, using other supported browsers can help us narrow down the cause of this unusual behavior.
