Every time I login to my account. I have to try many times. What can be the reason behind it??
Did you got any error after first login?
Can you try booting into Safe Mode and revert back to normal mode, see if issue still persists.
When you log in, open a notepad file and check if all of your keyboard keys are working correctly.
If one of them isn't actuating properly, this would cause what you are describing.
