Hi Mike Tran,
Thank you for posting in the Q&A Forums.
This can be due to a variety of reasons such as system updates, software conflicts or misconfiguration. Below are some possible steps and suggestions for resolution:
Windows Explorer is responsible for managing the taskbar and desktop icons, etc. If it has problems, it may cause the taskbar icons to disappear. You can try restarting Windows Explorer to fix this issue:
Press Ctrl+Shift+Esc to open Task Manager.
Find the "Windows Explorer" process in the "Processes" tab.
Right-click on it and select "Restart".
Make sure you have the latest version of Office and Windows 11, as Microsoft may fix such issues with an update.
Best regards
NeuviJ
