Why won't my drive take in discs?

Hello, I have had problems with my PS4 Slim disc drive not taking in discs for a while now.

It happened when i someday noticed there was a disc still in my playstation but it didn't read it nor would it eject it. So i used the manual ejection screw to get it out.

From then onwards the Playstation would not let me insert discs anymore. Even if i manually unscrew everything and put in a disc into the drive, it wont read it when the Playstation is booted up.

I have watched numerous videos and read articles on this, other forum posts including but nothing seems to work.

However there's a couple of things I've noticed looking at other people's drives and just trying out things with mine that seem a bit suspicious.

1.

There's white geerwheels on the left, which the left roller in the front is connected to aswell. Those seem to be completely stuck because the one second to the front one (the front one is the one attached to the left roller) does not want to move.

2.

The big white plastic thing on the left is completely immovable, which seems weird because there seems to be a spring attached to it??

3.

There's somewhat of a white lever? attached to the white plastic thing, it looks somewhat like a half circle. (It's positioned in the back to the left)

This thing, what i assume to be some kind of a lever is completely immovable, probably because the white plastic part on the left is aswell, however mine seems to be in a different position than others that ive seen are in? Its pulled somewhat towards the back, so it makes a disc fit in, so i assume this lever gets pushed back when a disc is inserted, however there is none inserted.

I hope anyone can help, thanks in advance!
