I recently took out the CPU from the motherboard to apply thermal paste on it for my laptop. When I put it back in, the locking tab wouldn't allow me to fully turn to unlock it.
Here is an image when it is fully locked without the CPU.

Here is an image where the locking tab is stuck and cannot fully lock with the CPU.

What can be the problem? Why can't I fully twist it to the lock side. Thank you.
