Hi point,
Thanks for your post. Based on my research, there are several reasons that could cause the Start menu and taskbar to stop working and fail.
- Corrupt system files
- Installed faulty or incompatible software
- Outdated OS
- Lack of system memory
- Hidden taskbar
You can refer the following article to see the methods of repairing.
