Ok so i found somewhat a solution to this problem. It is probably not the ideal solution but it alteast will keep your laptop from falling apart for hopefully a good while.
As you can see in the following pictures i had this exact same issue
So what i did to 'fix' it was to use 2 washers and 2 midlong laptop screws.
Then the idea was to simply put the washers on top of the base and screw the screws in, in this way using the base itself as support for the upperside of the laptop.
I then realized on one side that screw hole itself it actually also broken off and somewhere being loose in the laptop, i managed to get the broken pieces out of there.
So if your screw holes itself are intact you can just use something like the screws you can see in the picture above, this also worked on one side of my laptop, but since on the other side the screw hole itself is broken off, i decided to use a bigger screw and use the metal plate inside the laptop itself to screw it in.
This is the result:
And as you can see, it is holding together right now, and will atleast keep the laptop from falling apart for now.
