Hello the sunny, welcome to the Microsoft Community!
According to your feedback, you are experiencing multiple desktops open in Task View, causing constant crashes
I would like to check with you what is the crash message that is appearing on your computer?
You can try right-clicking on the taskbar to open Task Manager
Close the processes you don't need
Reduce the pressure on the task view
Then close the task view to see if it solves your problem.
You can upload a screenshot of your computer crashing.
and see if I can provide you with some solutions
I hope the above information is helpful
